Gender Roles Of Herland - 874 Words

Gender roles in Herland . After reading different articles and â€Å"Herland†, written in 1915 by Gilman, I have been thinking about this question that what would a world without man be like? On the contrary, what would a world without woman be look like? Gilman in her fairy novel, described three men landing in a country where there are only women are living there. A fairy land with cooperation , peace , wisdom and achievement. The characters in this book seem to have been chosen carefully. Terry is a man who believes a woman’s place in the world is in the house cooking and serving the man. Jeff themas who thinks that the woman are to be idolized and protected. And finally Van, who seems to be between the other two at the beginning but he changes his wive as the book goes on. These three men decided to discover a hidden land populated entirely by women. Women in Herland have been reproducing with the air, apparently, birthing babies without men, and they all are indepe ndent of sexual friendships. In Herland, women are fully successful in their socitey with their production , education, and health. They are strong and they can make changes when things aren’t working for them. Their religion is unifying and it’s based on unique values that bringing them all together in an exclusive community. Everyone has a place and a value. They built up their own society without any man, and Gilman was really successful to picture a feminism view in her readers’ mind.

The Republic By Plato - 1341 Words

In book X of The Republic, Plato uses Socrates as his voice to discuss the topic of poetry in his ideal society. While he sees music and gymnastics as vital parts of society, he sees poetry as something that’s not only unnecessary, but also harmful. Glaucon is surprised by this and questions the reasons Socrates has this way of thinking. Socrates states that â€Å"all such poetry is likely to distort the thought of anyone who hears it, unless he has the knowledge of what it is really like†. Here, Socrates is stating that the main reason poetry should be banished is due to the fact that it’s merely an imitation of true knowledge and since it’s not true knowledge itself, it can provide a warped version of what that knowledge is. There are several other reasons why Plato thinks that banishing poetry would be more beneficial to society. To him, an imitation, no matter how good, will always be inferior to the original. One example Plato would possibly use is a house. If someone tried to draw a picture of the house would the picture match perfectly with the house? The answer to that is no. The reason for this is that the picture could be drawn only from one side and if the house was drawn from another angle, it would look different. Also, the picture could be missing the features that surround the house such as trees, bushes, and walkways. The picture of the house would only show part of the whole house, thus displaying that part of the truth doesn’t show the whole truth.

Understanding Of Cerebral Hemodynamics Health And Social Care Essay Free Essays

string(122) " first portion is concerned with the harm of encephalon parts due to the occlusion or slowing of intellectual blood flow\." For the supratentorial encephalon, normal perfusion values, such as intellectual blood flow, intellectual blood volume and intend theodolite clip have been established utilizing the gilded criterion, 15O antielectron emanation imaging ( PET ) [ 9-11 ] . With regard to the posterior pit, there has been really small work in set uping normative flow values. There are merely two surveies utilizing 15O PET that study flow values in the posterior pit [ 12, 13 ] . We will write a custom essay sample on Understanding Of Cerebral Hemodynamics Health And Social Care Essay or any similar topic only for you Order Now 15O PET is comparatively unavailable in most states due to the demand for an onsite cyclotron. Consequently, CT and MR perfusion have become the most widely used methods for rating of intellectual perfusion in patients showing with shot, tumour or devolution [ 14-17 ] . Standard CT A ; MR perfusion techniques are semi-quantitative, nevertheless, several surveies have compared them to PET, and turn out their dependability for appraisal of the supratentorial encephalon [ 18-21 ] . Normal blood flow values of the posterior pit constructions utilizing CT or MR perfusion imaging have non been determined nevertheless ; hence doing judgements of unnatural flow and hemodynamics hard at best. Lin et al investigated crossed intellectual cerebellar diaschisis in acute shot patients in the cerebellum utilizing MR perfusion and concluded that this technique is a dependable, efficient and a more accessible alternate to PET [ 22 ] . However they did non set up normative values. The intent of this survey is to set up perfusion mention values in the posterior pit, utilizing a quantitative dynamic susceptibleness contrast ( DSC ) MRI perfusion scan, auxiliary to the perfusion values antecedently quantified with PET. Before showing our survey it is high to briefly reexamine the different capable affairs concomitant to our survey. We will hence hold a expression at the encephalon: its map and rule blood supply ; so continue with a short scrutiny of the chief pathogenesis impacting both, the supratentorial every bit good as the infratentorial parts of the encephalon. We will so hold a closer expression at these two different parts by researching the chief anatomical characteristics, physiological maps and chief pathologies ( vascular and neoplastic ) . Further, we will analyze the different encephalon perfusion techniques available today in respects to their advantages and disadvantages and eventually subtract the principle of our survey in visible radiation of the information given supra. Merely so, we will come in the nucleus of this work by sing the stuff and methods, showing our consequence and discoursing our findings. The Brain The human encephalon is the Centre of the human nervous system and is a extremely complex organ. It can be subdivided into two parts, the supratentorial part and the infratentorial part, located below the tentorium cerebelli. The supratentorial part contains the cerebrum consisting of the telencephalon and the interbrain. The telencephalon includes the intellectual cerebral mantle, subcortical white affair, and the basal ganglia. The major subdivisions of the interbrain are the thalamus and hypothalamus. The infratentorial part encloses the brain-stem dwelling of the mesencephalon ( midbrain ) , Ponss, and myelin oblongata ; and the cerebellum including the vermis and two sidelong lobes ( Fig. 1 ) . These infinites are filled with cerebrospinal fluid ( CSF ) . [ 23 ] Figure 1: The Central Nervous System brain.gif Beginning: Waxman SG: Clinical Neuroanatomy, 26e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5273762. The encephalon is formed by eight interrelated castanetss constructing the cranial pit. These castanetss are: the frontlet, occipital, sphenoid and ethmoid castanetss, and two each of the parietal and temporal castanetss. The cranial pit can be separated into two distinguishable parts: the interior surface and the floor, the latter includes three pit: the front tooth, in-between and posterior cranial pit. [ 24 ] The supratentorial portion of the encephalon is the besieging of ground ; perceiver of higher-order thought ; sing and memorising. It besides supervises the organic structure ‘s actions and reactions to intrinsic and extrinsic urges by analysing and reacting to the different informations from the sensory and motor tracts. The infratentorial portion of the encephalon is in charge of the autonomic procedures, commanding critical maps such as external respiration and bosom round and other indispensable maps. It besides takes attention of the organic structure ‘s sense of equilibrium, position and consecutive motions. The encephalon is capable to different sort of diseases including: cerebrovascular, neoplastic, infective, and degenerative and injury. Genetically based diseases including Multiple Sclerosis, Parkinson, Huntington Chorea and others are besides common, every bit good as psychiatric diseases such as depression, schizophrenic disorder and others. Blood Supply The cerebrovascular system delivers energy substrates and O and removes metabolic by-products. The encephalon histories for merely 2 per centum of entire organic structure weight, but consumes 20 per centum of the organic structure ‘s entire O demand and 15 per centum of entire cardiac end product. [ 25 ] The arterial blood for the encephalon enters the cranial pit by two braces of big vass: the vertebral arterias, originating from the subclavian arterias and the internal carotid arterias, ramifying off the common carotids ( Fig. 2 ) . The Vertebral Arterial System It supplies the brain-stem, cerebellum, occipital lobe, and parts of the thalamus. After go throughing through the hiatuss magnum in the base of the skull, the two vertebral arterias form a individual vas, the basilar arteria ( BA ) . This vas terminates as the left and right posterior intellectual arterias ( PCA ) . The little penetrating arterias, which branch off the basilar arteria, supply critical Centres in the brain-stem. [ 23 ] The Carotids They supply the balance of the cerebrum. The carotids form the circle of Willis. They are interrelated via the anterior intellectual arterias and the anterior communication arteria. They are besides connected to the PCAs of the vertebral system by two posterior pass oning arterias ( PcA ) .

Pathogenesis There are several implicit in causes for the damage of the encephalon ‘s normal map. In this subdivision we will hold a general overview of the cerebrovascular ( stoke, arteriovenous deformities, aneurisms ) and neoplastic pathogenesis of the encephalon. Cerebrovascular Diseases This first portion is concerned with the harm of encephalon parts due to the occlusion or slowing of intellectual blood flow. You read "Understanding Of Cerebral Hemodynamics Health And Social Care Essay" in category "Essay examples" We will see three major causes: shot, arteriovenous deformities ( AVM ) and aneurysm. We intentionally excluded legion other upsets such as reversible ischaemia, hypertensive brain disorder, or venous thrombosis as this would excel the range of this survey. Stroke By and large shot is a syndrome characterized by the acute oncoming of a neurologic shortage that persists for at least 24 hours, reflects focal engagement of the cardinal nervous system ( CNS ) , and is the consequence of a perturbation of the intellectual circulation ( loss of O and glucose substrates ) . [ 26 ] Basically, it refers to any disease procedure that disrupts blood flow to a focal part of the encephalon and that may be ischaemic or hemorrhagic in nature. The bulk ( 80 % ) are ischaemic in nature with the balance caused by bleeding within the cranial pit. [ 26 ] In the undermentioned subdivision we will define the ischaemic and haemorrhagic shots. Ischemic Stroke Ischemic stroke can be subdivided into three major etiologies: Thrombosis [ 26 ] It is the most common and nowadayss as a consequence of narrowing of the vascular lms. As a effect, blood flow decelerates and the high viscousness consequences in platelet adhesion and finally in coagulum formation. Atherosclerosis, particularly the big extracranial arterias in the cervix ( internal carotid arterias ) but besides intracranial arterias ( in-between intellectual arteria, BA ) , remains the cardinal cause of focal intellectual ischaemia. The most of import hazard factors for coronary artery disease taking to shot are: Systolic or diastolic high blood pressure Diabetess mellitus Elevated serum cholesterin and triglycerides Smoking Other causes of thrombotic shot include: Infections Autoimmune diseases Genetically based diseases Thrombotic shots normally evolve slightly easy over several proceedingss or hours. Embolism [ 26 ] When vascular lms stuff is fragmented and released, normally from a proximal beginning, it drifts into a narrower distal vas and obstructs blood flow. Contrary to the pathogenesis of thrombosis, the occluded vas is non pathologically attained. Cardiac beginnings of emboli include: Valvular floras Mural thrombi ( caused by atrial fibrillation, myocardial infarction, or dysrhythmias ) Paradoxical emboli ( caused by an atrial or ventricular septate defect ) Cardiac tumours ( myxomas ) Rarer causes of embolic shot include: Fat emboli Particulate emboli from endovenous drug injection Septic emboli Yet the bulk of emboli enter the anterior circulation instead than the posterior circulation. [ 26 ] Most embolic shots characteristically occur all of a sudden, and the shortage reaches its extremum about at one time. Figure 3 shows the most of import sites of thrombotic and embolic occlusion. Figure 3: Sites of Thrombotic and Embolic Occlusions in the Cerebrovascular Circulation Atheroprdelection.gif Beginning: Simon RP, Greenberg DA, Aminoff MJ: Clinical Neurology, 7e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5150807. Hypoperfusion [ 26 ] It is typically caused by cardiac failure and less common mechanism of ischaemic shot. Hypoperfusion leads to a more diffuse hurt form compared to thrombosis or intercalation and is typically located in watershed parts at the fringe of the intellectual vascular supply districts. Clearly, most cerebrovascular disease can be attributed to coronary artery disease and chronic high blood pressure. Until ways are found to forestall or command them, vascular disease of the encephalon will go on to be a major cause of morbidity and mortality. [ 26 ] Hemorrhagic Stroke Hemorrhagic shots are typically divided into two subtypes: Intracerebral bleeding [ 27 ] Intracerebral bleeding ( ICH ) is the most common signifier, particularly intraparenchymal bleeding, shed blooding occurs straight into encephalon parenchyma from little arteriolas antecedently weakened by elevated blood force per unit area. Leading hazard factor are: Increasing age History of shot But other factors are besides relevant, including: Race ( Asians and Blacks ) , Tobacco maltreatment Alcohol maltreatment Amyloidosis Use of decoagulant Use of clot busters ICHs chiefly occur while the patient is awake. It usually presents as an disconnected oncoming of focal neurologic shortage, which worsens over the following 30-90 min. Further the degree of consciousness diminishes and marks of increased ICP, such as concern and purging nowadays. Nontraumatic subarachnoid bleeding [ 25 ] Nontraumatic subarachnoid bleedings ( SAH ) are blood leaks from a intellectual vas into the subarachnoid infinite. SAHs consequence from berry aneurysm rupture, most normally happening at arterial bifurcations, or rupture of an arteriovenous deformity. Arteriovenous Deformity AVMs consists of a tangle of dilated vass that form an unnatural communicating between the arterial and venous systems without a capillary bed intervening. These developmental abnormalcies represent continuity of an embryologic form of blood vass and non a tumor, but the constitutional vass may proliferate and enlarge with the transition of clip. [ 28, 29 ] True vascular deformities vary in size from a little defect a few millimetres in diameter prevarication in the cerebral mantle or white affair to a immense mass of Byzantine channels representing an auriculoventricular shunt of sufficient magnitude to raise cardiac end product. The tangled blood vass interposed between arterias and venas are abnormally thin and do non hold the construction of normal arterias or venas. [ 28, 29 ] AVMs occur in all parts of the cerebrum, brain-stem, and cerebellum ( and spinal cord ) , but the larger 1s are more often found in the cardinal portion of a intellectual hemisphere. Typically, intellectual arteriovenous deformities are supratentorial, normally lying in the district of the in-between intellectual arteria. Generally, shed blooding or ictuss are the chief manners of presentation. [ 28, 29 ] Aneurysm Aneurysms, more exactly saccular or â€Å" berry † aneurisms take the signifier of little, thin-walled blisters stick outing from arterias of the circle of Willis or its major subdivisions ( Fig. 4 ) . Approximately 85 % of aneurysms arise from the anterior circulation and 15 % from the posterior circulation. [ 29, 30 ] Generally, those that rupture normally have a diameter of 10 millimeter or more. Their rupture causes a implosion therapy of the subarachnoid infinite, doing SAH. Because the meningeal liners of the encephalon are sensitive, SAH normally consequences in a sudden, terrible â€Å" thunderclap † concern or described as â€Å" the worst concern of my life † . As a regulation, the aneurisms are located at vessel bifurcations and are by and large presumed to ensue from developmental defects in the media and elastica of the arterias. Showing neurologic symptoms may run from mild concern to coma to sudden decease. [ 29, 30 ] Figure 4: Sites of Aneurysms in the Cerebrovascular Circulation aneurysm.gif Beginning: Ropper AH, Samuels MA: Adams and Victor ‘s Principles of Neurology, 9e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=3637579. Intracranial Tumors The importance of tumours of the CNS derives from: Their great assortment Numerous neurologic symptoms ( caused by their size, location, and invasive qualities ) The devastation and supplanting of tissues The lift of intracranial force per unit area Their deadliness The histogenetic theory by Bailey and Cushing, predominant in recent old ages, argues that most tumours arise from neoplastic transmutation of mature grownup cells ( particularly glia cells ) , called dedifferentiation. [ 31 ] During this procedure a normal astrocyte, oligodendrocyte, microgliocyte, or ependymocyte is transformed into a neoplastic cell and becomes bit by bit, with every mitosis, anaplastic. The grade of malignance is relative to the uniform province of the initial cells. [ 29 ] Many factors play a function in the biological science of encephalon tumours. Several heightening determiners can be identified: Age Certain encephalon tumours ( primary or secondary ) are much more frequent than others and are prone to happen in peculiar age groups. For case medulloblastomas, polar glioblastoma, ocular nervus gliomas, and pinealomas occur chiefly before the age of 20 old ages. On the other manus, meningiomas and spongioblastoma are most frequent in patients above 60 old ages. As a regulation, secondary metastatic tumours are more common in grownups and primary encephalon tumours more common in kids. [ 29 ] Geneticss Heredity besides figures greatly in the generation of certain tumours, peculiarly retinoblastomas, neurilemoma, and hemangioblastomas. Neurofibromatosis and tuberous induration and the cerebellar hemangioblastoma of von Hippel-Lindau are the best illustrations of a familial determiner. [ 29 ] Viruss Harmonizing to Levine the virus is believed to coerce the cell to divert from its normal activity in its replicative rhythm. [ 32 ] Such viruses are called transforming genes, as they are able to modify the cellular genome. Oncogenes fundamentally halt the cells self-destruction ( programmed cell death ) map and heighten the asocial proliferation of the cell, doing tumours ( e.g. AIDS ) . Metastasiss Certain malignant neoplastic diseases ( chest, lung, melanoma, nephritic cell malignant neoplastic disease ) display a inclination to metastasise to nervous tissue. [ 29 ] Paraneoplasies Systemic tumors produce particular autoantibodies with distant effects on the CNS. These distant effects are called paraneoplasias and most normally are the initial or even merely clinical manifestation of the implicit in tumor. Some primary intracranial and spinal tumours, such as craniopharyngioma, meningioma, and schwannoma, have a temperament to turn in peculiar parts of the cranial pit, thereby bring forthing extremely characteristic neurologic syndromes. [ 29 ] As for nosologies, the location ( supra vs. infratentorial and intraaxial vs. extraaxial ) every bit good as the age group ( child vs. grownup ) are of import appraisal characteristics. For case supratentorial tumours normally present with focal neurologic shortages, concern or ictus ; whereas infratentorial tumours preponderantly present with elevated ICP ( hydrocephaly and 4th ventricle compaction ) , taking to sickness, purging or double vision, seldom doing ictuss. [ 30 ] Therefore following to the initial clinical appraisal, imagination has become an of import diagnostic tool. This short reappraisal of the chief pathomechanisms, underlying cerebrovascular or intracranial neoplastic diseases, shows clearly the importance of distinguishing between upsets impacting the supratentorial and infratentorial encephalon parts. Because of the different clinical presentations and symptoms and the subsequent difference in diagnostic and therapy it becomes constantly of import to concentrate in the following subdivision on the anatomical divisions and map every bit good as blood supply of each part individually. We will besides analyze the major associated cerebrovascular and neoplastic pathologies in order to better understand the significance our survey. Supratentorial Brain The cerebrum is lodged by the center and anterior pit. The two intellectual hemispheres constitute the largest division of the encephalon. The specialised maps of a cortical part arise from the interplay between corticocortical systems and subcortical systems and a basic intracortical processing faculty. [ 33 ] Regions of the cerebral mantle are classified in several ways [ 34 ] : By the mode of information processed ( e.g. , sensory, motor and associational ) By anatomical place ( frontal, temporal, parietal, and occipital ) By the geometric relationship between cell types in the major cortical beds We will analyze the intellectual cerebral mantle by anatomical place ( frontal, temporal, parietal and occipital ) and for descriptive intents we will shortly exemplify the chief implicit in syndromes. But we will foremost hold a expression at two functional parts viz. the limbic system and the interbrain. Limbic System The limbic system encompasses the hippocampal formation, amygdaloid composite, septum, olfactive karyon, and selected karyon of the interbrain, and is the beginning of complex emotional and motivational maps, every bit good as long term memory and smell. It forms the interior boundary line of the cerebral mantle. [ 34 ] The hippocampus, for case, is important to the formation of recent memory, since this map is lost in patients with extended bilateral harm to the hippocampus. [ 34 ] Diencephalon The interbrain encompasses the thalamus and hypothalamus. The nerve cells of the thalamus are arranged into distinguishable bunchs, or nuclei. These nuclei act as relays between the incoming centripetal tracts and the cerebral mantle, between the distinct parts of the thalamus and the hypothalamus, and between the basal ganglia and the association parts of the intellectual cerebral mantle. The thalamic karyon and the basal ganglia besides exert regulative control over splanchnic maps ; aphagia ( inability to get down ) and adipsia ( absence of thirst ) , every bit good as general sensory disregard. The basal ganglia, for case, organize an indispensable regulative section of the extrapyramidal motor system. Damage to the extrapyramidal causes upsets characterized by nonvoluntary motions, such as the shudders and rigidness of Parkinson ‘s disease or the unmanageable limb motions of Huntington ‘s chorea. Similarly, the hypothalamus is the chief integrating part for the full autonomic nervous system and regulates organic structure temperature, H2O balance, intermediary metamorphosis, blood force per unit area, sexual and circadian rhythms, secernment of the anterior pituitary, slumber, and emotion. [ 34 ] Cerebral Cortex Brodmann distinguished 47 different functional zones of intellectual cerebral mantle, and although it is referred to with much contention and the informations were ne’er published, his system is still in usage today. In general one must see the cerebral mantle as a heterogenous compound of many interrelated anatomic systems, Certain parts of the cerebrum are committed to particular perceptual, motor, sensory, mnemonic, and lingual activities. [ 29 ] For case the integrating of cortical with subcortical constructions is reflected in commanded motions. A simple motion of the manus requires activation of the premotor cerebral mantle, which undertakings to the striate body and cerebellum and back to the motor cerebral mantle via a complex thalamic circuitry before the direct and indirect corticospinal tracts can trip certain combinations of spinal motor nerve cells. [ 29 ] Thus interregional connexions of the cerebrum are required for all natural sensorimotor maps. In the same manner, their devastation disinhibits or â€Å" releases † other countries. For case parietal lesions result in complex turning away motions to contactual stimulation. [ 29 ] Finally the intellectual cerebral mantles besides provide supervisory integrating of the autonomic nervous system and incorporate bodily and vegetive maps, including those of the cardiovascular and GI systems. [ 34 ] Because of this interregional connexion damage of one part may ensue in the malfunctioning of other parts as seen in patients with shot, tumour or devolution. Here is a speedy overview of the major maps of the cerebrum: [ 35 ] Motion The cerebrum directs the witting or voluntary motor maps of the organic structure. These maps originate within the primary motor cerebral mantle and other frontal lobe motor countries where actions are planned. Centripetal processing The primary centripetal countries of the intellectual cerebral mantle receive and procedure ocular, audile, somatosensory, gustatory, and olfactive information. Together with association cortical countries, these encephalon parts synthesize centripetal information into our perceptual experiences of the universe. Smell The olfactive sensory system is alone in the sense that nerve cells in the olfactory bulb send their axons straight to the olfactory cerebral mantle, instead than to the thalamus foremost. Language and communicating Address and linguistic communication are chiefly attributed to parts of the intellectual cerebral mantle. Motor parts of linguistic communication are attributed to Broca ‘s country within the frontal lobe. Speech comprehension is attributed to Wernicke ‘s country, at the temporal-parietal lobe junction. Learning and memory Explicit or declaratory memory formation is attributed to the hippocampus and associated parts of the median temporal lobe. Implicit or procedural memory, such as complex motor behaviours, involves the basal ganglia. Finally, after this short functional reappraisal of the chief intellectual parts and showing the significance of interconnectivity between cortical, subcortical and associational countries, the following subdivision will analyze the map and blood supply of the chief anatomic place ( Fig. 5 ) , viz. the frontlet, parietal, temporal and occipital lobes. Figure 5: The Brain Separated by Lobes hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=ropp9 A ; filename= % 09ropp9_c022f001.gif Beginning: Ropper AH, Samuels MA: Adams and Victor ‘s Principles of Neurology, 9e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=3633619 Frontal Lobe In short the frontal lobe, situated in the anterior half of the encephalon, is in a general sense committed to the planning, induction, monitoring, and executing of all intellectual activity. Harmonizing to Luria et Al. this was competently summarized by as â€Å" purposive behaviour. â€Å" [ 36 ] Consequently, lesions of the frontal lobes consequence in damage of back-to-back planning, an inability to keep consecutive relationships of events, and to switch easy from one mental activity to another. In the emotional domain, frontal lobe lesions may do anhedonia[ 1 ], apathy[ 2 ], and loss of self-denial, disinhibited societal behaviour. [ 29 ] For descriptive intents, the clinical effects of frontal lobe lesions can be grouped under the undermentioned classs: [ 29 ] Motor abnormalcies related to the motor cerebral mantle Address and linguistic communication upsets related to the dominant frontal lobe Incontinence of vesica and intestine Damage of capacity for purposive sustained mental activity Inability to switch from one line of idea or action to another Akinesis[ 3 ]and deficiency of enterprise and spontaneousness Changes in personality, peculiarly in temper and self-denial Distinctive abnormalcy of pace In decision, it seems clear, that the frontal lobe is at the intersection of all motor activities. This applies non merely to willed motion but to all postural reactions and accustomed activity every bit good. Blood Supply Blood is supplied by the anterior intellectual arteria ( ACA ) and to the deep parts by the superior division of the in-between intellectual arteria ( MCA ) . The implicit in deep white affair is supplied by little penetrating arterias, called lenticulostriate vass that originate straight from the MCA. [ 29 ] Temporal Lobe The symptoms that arise as a effect of disease of the temporal lobes may be divided into: [ 29 ] Disorders of the particular senses: Ocular: temporal lobe abnormalcies may falsify ocular perceptual experience ; seen objects may look excessively big ( macropsia ) or little ( micropsia ) ; ocular hallucinations of complex signifier, including 1s of the patient himself ( autoscopy ) Auditory: Wernicke ‘s aphasia[ 4 ], ensuing in agnosias ( inability to acknowledge sounds, different musical notes or words ) and audile verbal agnosia ( failure in decrypting the acoustic signals of address and change overing them into apprehensible words ) , semblances and hallucinations Olfactory and gustatory: perturbation of odor and gustatory sensation Time perceptual experience: province of confusion Memory: amnestic syndrome Emotion A ; behaviour: cardinal function of the temporal lobe, notably its hippocampal and limbic parts, consequence in lost natural emotional reactions such as fright and are of cardinal importance for linguistic communication, memory and learning maps. Blood Supply The inferior subdivision of the in-between intellectual arteria and the temporal subdivision of the PCA supplies blood to the temporal lobe ( median and inferior facets, including the hippocampus ) . [ 29 ] Parietal Lobe Lesions in the parietal lobe show a scope of assorted clinical phenomena. The nucleus job represents agnosia, associated with complex behavioural alterations. In this context the term agnosia becomes synonym for a loss of more complex incorporate maps and mental symbolisms. These syndromes include [ 29 ] : Loss of the ability to cipher Loss to distinguish left from right Loss to compose words Apraxia[ 5 ] Blood Supply The parietal lobe is supplied by the MCA, the inferior and superior divisions providing the inferior and superior lobules, severally. [ 29 ] Occipital Lobe The most familiar clinical abnormalcy ensuing from a lesion of one occipital lobe is a contralateral homonymic hemianopsia. Bilateral lesions of the occipital poles, as in intercalation of the PCAs, consequence in bilateral hemianopsia and cortical sightlessness. Many of the complex behavioural defects affecting ocular map are caused by lesions at the junctions of the occipital and parietal or temporal lobes. Damage to the occipital lobe my consequence in assorted defects including [ 29 ] : Ocular anosognosia ( Anton Syndrome ) : Denial of sightlessness by a patient who evidently, can non see or the patient is able to see little objects but claims to be unsighted Ocular semblances ( metamorphopsias ) : Distortions of signifier, size, motion, or colour Ocular hallucinations: They may be simple or complex, and both types have sensory every bit good as cognitive facets, e.g. flashes of visible radiation, colourss, aglow points, stars, multiple visible radiations ( like tapers ) , and geometric signifiers ( circles, squares, and hexagons ) . They may be stationary or traveling ( zigzag, oscillations, quivers, or pulsings ) . Agnosia: e.g. ocular simultanagnosia, which describes an inability to hold on the sense of the multiple constituents of a entire ocular scene despite maintained ability to place single inside informations. Balint ‘s Syndrome: [ 27 ] it involves shortages in the orderly visuomotor scanning of the environment ( oculomotor apraxia ) and in accurate manual making toward ocular marks ( ocular ataxy ) . The 3rd and most dramatic constituent is known as simultanagnosia and reflects an inability to incorporate ocular information in the centre of regard with more peripheral information. The patient with simultanagnosia â€Å" misses the wood for the trees. † Blood Supply The occipital lobes are supplied about entirely by the PCAs and their subdivisions. A little country of the occipital pole receives blood supply from the inferior division of the MCA. [ 29 ] In the undermentioned subdivision we will look at the supratentorial diseases of our patients with particular focal point on the tumour patients, and have a speedy expression at crossed cerebellar diaschisis and encephalocele. Supratentorial Tumors As seen in the old subdivision, a broad assortment of pathomechanisms affect the tumorgenesis in the encephalon. Primary benign and malignant tumours arise from the assorted elements of the CNS and tumours metastasize to the CNS from many primary beginnings. In the undermentioned subdivision we will look at the chief survey related malignances. Glial Tumors Glial cells provide the anatomic and physiologic support for nerve cells and their procedures in the encephalon. The several types of glial cells give rise to distinct primary CNS tumor. We will see the astrocytoma and the oligodendroglioma. Astrocytomas Astrocytoma is the most common primary CNS tumor. [ 37 ] The term glioma is frequently used to mention to astrocytomas specifically, excepting other glial tumours. Here are the chief features: [ 37 ] Rating: I and II are low-grade astrocytoma, III anaplastic astrocytoma, and IV glioblastoma multiforme ( GBM ) Histological characteristics: associated with class III and II include hypercellularity, atomic atypia, and endovascular hyperplasia Invasiveness: aggressive ; infiltrates adjacent encephalon tissue Necrosis: present merely with GBMs Surgical therapy: gross entire resection is state-of-the-art ; nevertheless motor cerebral mantle, linguistic communication Centres, deep or midline constructions, or brain-stem location make this impossible without lay waste toing neurologic shortage Radiation therapy: neoadjuvant radiation therapy improves endurance for all classs Chemotherapy may be considered, but is of limited efficaciousness so far Oligodendroglioma Oligodendroglioma histories for about 10 % of gliomas. Here are the chief features: [ 37 ] Present frequently with ictuss Calcifications and bleeding on CT or MR imaging suggest the diagnosing Rating: I to IV ; class indicates forecast Prognosis is better overall than for astrocytomas ; average endurance ranges from 2 to 7 old ages for highest and lowest class tumours, severally Surgical therapy: aggressive resection improves survival Chemotherpay: many patients are antiphonal to chemotherapy Radiation therapy: has non been clearly shown to protract endurance Metastatic Tumors Drawn-out malignant neoplastic disease patient endurance and improved CNS imagination have increased the likeliness of naming intellectual metastases. The beginnings of most intellectual metastases are ( in diminishing frequence ) : [ 37 ] Lung Breast Kidney GI piece of land Melanoma Main transit way of metastatic cells to the cerebrum is hematogenously. Other common locations are the cerebellum and the meninxs. Metastasiss are frequently really good circumscribed, unit of ammunition, and multiple. Pituitary Adenoma Pituitary adenomas arise from the anterior pituitary secretory organ ( anterior pituitary ) . Pituitary tumours may be: [ 37 ] Functional: secrete endocrinologically active compounds at diseased degrees ; diagnosed when the lesion is little due to endocrine disfunction Non-functional: secrete nil or inactive compounds ; diagnosed when the lesion is big doing ocular field shortages or panhypopituitarism Diagnostic pituitary tumours should be surgically removed, chiefly through the nose via the transsphenoidal attack. However, prolactin-secreting tumours ( prolactinomas ) normally shrink with dopaminergic therapy entirely. Particular Considerations Crossed Cerebellar Diaschisis Harmonizing to Feeney et Al. diaschisis signifies reduced partial encephalon map due to the break at a distant site of an afferent tract. [ 38 ] This afferent tract physiologically supplies background excitement to nerve cells, maintaining them in activity and therefore forestalling devolution of the latter. Crossed intellectual cerebellar diaschisis ( CCD ) was first described by Baron et Al. [ 39 ] As each cerebellar hemisphere is closely connected to the contralateral intellectual cerebral mantle, hurt ( e.g. shot, tumour, etc. ) to the supratentorial portion of the encephalon would impact the cerebellum. Basically, CCD is a province of cerebellar hypometabolism ( reduced blood flow and oxygen consumption ) due to the functional disjunction of the contralateral intellectual hemispheres as stated by Tien and Ashdown. [ 40 ] It is of import to see this fact when analysing the cerebellum with patients enduring from supratentorial diseases such as cerebrovascular diseases ( aneurisms, stroke, arterio-venous deformities ) or tumours as it is in our survey. Encephaloceles Hernia of encephalon encased in meninxs through the skull that forms an intracranial mass is referred to as encephalocele. Hernia of meninxs without encephalon tissue is referred to as a meningocele. More seldom, the tissue protrudes through the skull base into the fistulas. Treatment involves deletion of the herniated tissue and closing of the defect. Most patients with encephaloceles and meningoceles have impaired cognitive development. Patients with greater sums of herniated nervous tissue tend to hold more terrible cognitive shortages. [ 37 ] For better understanding the rational of our survey it is of import to hold a brief expression at the major posterior pit complaints. This subdivision will first analyze the chief anatomic and physiological characteristics and so turn to the most of import cerebrovascular diseases in the brain-stem and cerebellum including the chief shot syndromes ( ischaemic and haemorrhagic ) . After that we will look at the most common posterior pit associated tumours. Infratentorial Brain The brain-stem and cerebellum are lodged by the posterior pit. From all pit mentioned earlier this one is the largest and deepest of the three ( Fig. 6 ) . It is defined by following anatomical constructions [ 24 ] : The hiatuss magnum forms the cardinal portion of the floor and transmits: the myelin oblongata ; the go uping spinal parts of the accessary nervousnesss ; the two vertebral arterias ( VAs ) ; and the anterior and posterior spinal arterias The hypoglossal canal is situated above the anterolateral boundary of the hiatuss magnum and transmits: the nervus hypoglosus nervus ; and emissary venas Behind the hiatuss magnum are the inferior occipital foss? , which support the hemispheres of the cerebellum The jugular hiatuss is situated at that place. The anterior part transmits: the inferior petrosal fistula ; and the sigmoid fistula fall ining to organize each internal jugular vena. The posterior part transmits: the transverse fistula ; and some meningeal subdivisions from the occipital and go uping pharyngeal arterias. The intermediate part transmits: the glossopharyngeal ( IX ) ; the pneumogastric ( X ) ; and the accoutrement ( XI ) cranial nervousnesss Finally the internal acoustic meatus transmits: the facial and vestibulocochlearA nervousnesss ; and the internal auditory arteria. Figure 6: The Base of the Skull – upper surface Beginning: hypertext transfer protocol: //www.bartleby.com/107/47.html We will hold a closer expression at the larger anatomical divisions and supply a brief overview of encephalon maps and the most of import pathological changes to our survey. Brainstem The brain-stem is the portion of the CNS located between the spinal cord and the prosencephalon. It consists, from cranial to caudal, of the mesencephalon ( midbrain ) , Ponss ( metencephalon ) , and myelin oblongata ( myelencephalon ) . The three internal longitudinal divisions of the brain-stem are the tectum ( chiefly in the mesencephalon ) , tegmentum, and footing ( see Fig. 7 ) . The superior part of the rhomboid pit ( which forms the floor of the 4th ventricle ) extends over the Ponss, whereas the inferior part covers the unfastened part of the myelin. Three paired cerebellar peduncles ( inferior, in-between, and superior ) signifier connexions with the cerebellum. Finally the dorsal facet of the myelin shows four knolls: the two superior and the two inferior colliculi, jointly called the principal quadrigemina. These constructions enable the connexion between the intellectual hemispheres and thalamus-hypothalamus to the spinal cord, associating, via the reticulate formation ( part of grey affair in the tegmentum ) , peripheral sensory and motor events with higher degrees of nervous integrating. These â€Å" span parts † of the CNS are an highly of import portion of the encephalon, as they contain most of the karyon of the cranial nervousnesss, every bit good as the major influx and outflow piece of lands from the cerebral mantles and spinal cord. [ 23, 34 ] These include: The corticospinal piece of land The major motor piece of land The posterior column-medial fillet tract The spinothalamic piece of lands The brain-stem may functionally hence be divided into three chief centres, which are far from reciprocally sole: [ 23, 34 ] Conduit maps The lone manner for go uping piece of lands to make the thalamus or cerebellum ( or for falling piece of lands to make the spinal cord ) is through the brain-stem. Many of these piece of lands, nevertheless, are non straight-through personal businesss, and relay karyon in the brain-stem are often involved. Integrative maps The points of cardinal integrating for coordination of indispensable automatic Acts of the Apostless, such as swallowing and emesis, and those that involve the cardiovascular and respiratory systems ; these countries besides include the primary receptive parts for most splanchnic afferent centripetal information. The reticulate energizing system is indispensable for the ordinance of slumber, wakefulness, and degree of rousing, every bit good as for coordination of oculus motions. Cranial nervus map The karyon of cranial nervousnesss III through XII, except of the olfactory and ocular nervousnesss that project straight to the cerebrum and interbrain, severally, are besides located within the brain-stem. These nervousnesss relay the motor, sensory, and particular sense maps of the oculus, face, oral cavity, and pharynx. Figure 7: Drawing of the Divisions of the Brainstem – midsagittal plane hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=waxm A ; filename= % 09waxm_c007f004.gif Beginning: Waxman SG: Clinical Neuroanatomy, 26e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5273762 Blood Supply Here we look at the chief arterial short pantss providing the brain-stem, viz. the VA, the BA and the PCA ( see Fig. 8 ) . The Vertebral Artery The VAs are the main arterias of the myelin and the posterior inferior portion of the cerebellar hemisphere. The long circumferential subdivisions originating from the VAs and BAs are the posterior inferior cerebellar ( PICA ) , the anterior inferior cerebellar ( AICA ) , and the superior cerebellar arterias ( SCA ) and several smaller subdivisions, such as the pontine and internal auditory arterias. Short subdivisions originating from the long circumferential arterias penetrate the ventral brain-stem to provide the brain-stem motor tracts. [ 26 ] The VAs are most frequently occluded by atherothrombosis in their intracranial part. Because the VAs have a long extracranial class and base on balls through the cross procedures of C6 to C1 vertebrae before come ining the cranial pit, one might anticipate them to be capable to trauma, spondylotic compaction, and a assortment of other vertebral diseases. However arterial dissection is the most common other cause after vascular occlusion. [ 29 ] The Basilar Artery The BA normally arises from the junction of the mated VAs, though in some instances merely a individual VA is present. The BA courses over the ventral surface of the brain-stem to end at the degree of the mesencephalon, where it bifurcates to organize the PCAs. [ 26 ] The subdivisions can be divided as follows: [ 29 ] The paramedian subdivisions providing the Ponss The short circumferential providing the sidelong two-thirds of the Ponss and the center and superior cerebellar peduncles The long circumferential subdivisions ( SCA and AICA ) , which run laterally around the Ponss to make the cerebellar hemispheres The paramedian interpeduncular subdivisions at the bifurcation of the BA and beginnings of the PCAs providing the high mesencephalon and median subthalamic parts BA syndromes normally produce coma by impairing blood flow to the brain-stem reticulate energizing system. Thrombosis normally affects the mid-portion, and embolic occlusion the top of the basilar arteria. Virtually all patients present with some change of consciousness, and 50 % of patients are comatose at presentation with focal marks nowadays from the beginning. [ 26 ] Figure 8: Chief Arteries of the Brainstem – ventral position arteries3.gif Beginning: Waxman SG: Clinical Neuroanatomy, 26e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5272329. The Posterior Cerebral Artery The mated PCAs arise from the tip of the basilar arteria and provide the occipital intellectual cerebral mantle, median temporal lobes, thalamus, and rostral mesencephalon. Emboli in the BA tend to lodge at its vertex, where they can obstruct one or both PCAs. [ 26 ] Occlusion of the PCA produces a greater assortment of clinical effects than occlusion of any other arteria because both the upper brain-stem, which is crowded with of import constructions and the inferomedial parts of the temporal and occipital lobes lie within its supply. The site of the occlusion will find the location and extent of the ensuing infarct. [ 29 ] The collaterals of the chief arterial short pantss form four arterial groups ( anteromedial, anterolateral, sidelong, and posterior ) , which supply the brain-stem structures harmonizing to their point of incursion into the parenchyma. This categorization was devised by the anatomical work of Duvernoy ( 1999 ) . At each degree of the brain-stem, the beginning of these groups varies. The specific blood supply will be examined for each anatomical construction individually in the undermentioned subdivisions. [ 41, 42 ] In the following subdivision we will entirely concentrate on the cerebrovascular syndromes and neoplastic diseases impacting the posterior pit constructions. Therefore any syndrome resulting from the occlusion of the posterior intellectual arteria, although portion of the posterior circulation will non be dealt with as some syndromes affect the supratentorial portion of the encephalon ( thalamic hurting syndrome, Balint ‘s syndrome, etcaˆÂ ¦ ) resting hence outside the range of this concise reappraisal. Medulla Oblongata The myelin oblongata is the portion of the brain-stem that connects with the spinal cord. The medullary countries for the autonomic control of the circulation, bosom, and lungs are called the vital centres because harm to them is normally fatal. The afferent fibres to these centres originate in a figure of cases in specialised splanchnic receptors. The specialised receptors include non merely those of the carotid and aortal fistulas and organic structures but besides receptor cells that are located in the myelin itself. The motor responses are graded and adjusted and include bodily every bit good as splanchnic constituents. Swallowing, coughing, sneezing, gagging, and purging are besides automatic responses integrated in the myelin oblongata. [ 23, 24, 34 ] The myelin can be divided into three parts: [ 23, 24, 34 ] Caudal or closed part incorporating a cardinal canal uninterrupted with that of the spinal cord Rostral or unfastened part, in which the cardinal canal expands as the 4th ventricle Apex of the V-shaped caudal 4th ventricle, where it narrows into the cardinal canal, is called the obex. Further it is of import to separate the tracts that run through the myelin: [ 23, 24, 34 ] Ascending piece of lands The median fillet: carries centripetal information from the gracile and cuneate karyons to the thalamus for all right touch, quiver esthesis and proprioception. The spinoreticular: responsible for general reaction related to trouble such as waking up, affectional and vegetive maps. The ventral spinocerebellar tract: conveys proprioceptive information from the organic structure to the cerebellum. The spinothalamic piece of land: a centripetal tract arising in the spinal cord. It transmits information to the thalamus about hurting, temperature, scabies and petroleum touch. Descending piece of lands The corticospinal piece of land in the pyramid begins to traverse at the passage between myelin and spinal cord. It largely contains motor axons. It really consists of two separate piece of lands in the spinal cord: the sidelong corticospinal piece of land and the median corticospinal piece of land The falling spinal piece of land of the trigeminal nervus has its cell organic structures in the trigeminal ganglion. The fibres of the piece of land convey hurting, temperature, and crude touch esthesiss The median longitudinal fiber bundle is an of import tract involved with control of regard and caput motions The tectospinal piece of land relays urges commanding cervix and bole motions in response to ocular stimulation Blood Supply The arterial supply of the myelin comes from the VAs, the PICA and the anterior and posterior spinal arterias ( Fig. 9 ) . Follows the division by arterial groups: [ 42 ] The anteromedial group arises from the anterior spinal arteria or the anterior spinal and vertebral arterias The anterolateral group arises from the anterior spinal and vertebral arterias, anterior spinal and PICA or anterior spinal and VAs The sidelong group derives from the PICA or the VA The posterior group stems from the posterior spinal arteria or the PICA Figure 9: Arterial Supply of the Medulla hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=simo7 A ; filename= % 09simo7_c009f012d.gif Beginning: Simon RP, Greenberg DA, Aminoff MJ: Clinical Neurology, 7e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5151404. Medullary Infarcts These can be divided into sidelong and median medullary infarcts and a combination of both, hemimedullary infarct ( Fig. 10 ) . Lateral medullary infarct Harmonizing to Norrving et Al. the medullary infarct syndrome, is one of the most common brain-stem infarcts and histories for approximately 2 % of all admittances for acute shot. [ 43 ] The characteristic syndrome with dizziness is due to the occlusion of the VA barricading the sidelong myelin and inferior cerebellum ( PICA ) blood supply. It is besides called Wallenber syndrome, named after the doctor who foremost described it in 1895. It is about ever caused by infarction, with merely a little figure of instances being the consequence of bleeding, demyelination, or tumour. [ 29, 44 ] As stated by Currier et al. , symptoms typically consist of dizziness, sickness, purging, dysphagia, gruffness, and nystagmus in add-on to ipsilateral Horner syndrome ( ptosis, meiosis, enophthalmia, and loss of facial perspiration ) , ipsilateral limb ataxy, and damage of all centripetal modes over the face ever affecting hurting and temperature esthesis. [ 45 ] Further the corneal physiological reaction is frequently absent. Vertigo is common and is caused by a lesion in the vestibular karyon or their connexions. [ 29, 44 ] Medial medullary infarct Harmonizing to Vuilleumier et al. , Dejerine syndrome is comparatively rare, looking in one of 28 medullary infarcts in one series. The writer sees the cause of the infarct frequently in the atherothrombosis of the VA or the anterior spinal arteria ; the most common symptoms include contralateral hemiparesis ( seldom ipsilateral ) and a hemisensory shortage saving the face ; ipsilateral linguistic paresis or gawky lingua motions may on occasion be observed. [ 46 ] If it is one-sided, it is besides known as jumping nervus hypoglosus unilateral paralysis, depicting a province where the cranial nervus failing is on the same side as the lesion, but the organic structure palsy is on the contralateral side. [ 29 ] Figure 10: Lateral Medullary Syndrome and Alternating Hypoglossal Hemiplegia loadBinary2.gif Beginning: Waxman SG: Clinical Neuroanatomy, 26e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5272329. Hemimedullary infarct Hemimedullary infarct, besides called Reinhold ‘s syndrome, is rare. The authoritative clinical image of the hemimedullary syndrome is a combination of the symptoms of sidelong and median medullary infarcts. When the motor shortage is ipsilateral to the infarction, it may propose that dissection of the VA is the mechanism of the shot. In fact it includes all symptoms of Wallenberg ‘s syndrome in add-on to contralateral hemiparesis. [ 47 ] Other syndromes exist with many of the same characteristics, such as the AICA occlusion taking to infarction of the sidelong part of the caudal Ponss and the syndrome of sidelong rostral pontine infarction from SCA occlusion. But inside informations on these would excel the range of this brief overview Midbrain This is the part of the encephalon between the rhombencephalon and the interbrain – the rostral portion of the brain-stem. Its dorsal part is the tectum and its ventral part is the tegmentum ( including reticulate formation ) . The mesencephalon is the short, constricted part which connects the Ponss and cerebellum with the thalamencephalon and intellectual hemispheres. It contains cranial nervousnesss that stimulate maps such as vision ( lens form and pupil diameter ) and muscles commanding oculus motion. Besides maps such as hearing, organic structure motion and physiological reactions are being generated. Further the dopaminergic mesencephalon nerve cells are involved in many of import encephalon maps including affectional and cognitive undertakings. The anterior portion has the intellectual peduncle, which is a immense package of axons going from the intellectual cerebral mantle through the brain-stem transporting of import information for voluntary motor map. [ 23, 24, 34 ] The mesencephalon can be divided into: [ 23, 24, 34 ] Footing It is composed of a brace of cylindrical organic structures, the crus cerebri or intellectual peduncles, a monolithic fibre package that includes corticospinal, corticobulbar, and corticopontine tracts. Each peduncle consists of a dorsal and a ventral portion, separated by a profoundly pigmented lamina of grey substance, termed the substantia nigger. The substantia nigger ( whose cells contain neuromelanin ) receives afferent fibres from the intellectual cerebral mantle and the striate body and sends dopaminergic motorial fibres to the striate body. The substantia nigger plays a cardinal function in wages, dependence and motion control. Tegmentum It contains all the go uping piece of lands from the spinal cord or lower brain-stem and many of the falling systems. A big ruddy karyon receives crossed motorial fibres from the cerebellum and sends fibres to the thalamus and the contralateral spinal cord via the rubrospinal piece of land. The ruddy karyon is an of import constituent of motor coordination. Close to the periventricular grey affair lie the bilateral venue coeruleus karyon. Nerve cells in these karyons contain norepinephrine and undertaking widely to the cerebral mantle, hippocampus, thalamus, mesencephalon, cerebellum, Ponss, myelin, and spinal cord. These nerve cells regulate the sleep-wake rhythm and control arousal ; they may besides modulate the sensitiveness of centripetal karyon. Tectum It consists of four rounded distinctions, named the principal quadrigemina, who are arranged in braces ( superior and inferior colliculi ) . These paired rounded puffinesss have different maps. The superior colliculi contain nerve cells that receive input from the retina and the ocular cerebral mantle and participates in a assortment of optic physiological reactions, peculiarly the trailing of objects in the ocular field. The inferior colliculi are involved in auditory physiological reactions and in finding the side on which a sound originates. The colliculi contribute to the formation of the crossed tectospinal piece of lands, which are involved in winking and head-turning physiological reactions after sudden sounds or ocular images. Periaqueductal Gray Matter It contains falling autonomic piece of lands every bit good as endorphin-producing cells that suppress hurting. Blood Supply Five arterial short pantss supply the arterial mesencephalon groups, from underside to exceed, SCA ( chiefly the median subdivision ) , the collicular arteria, the posteromedial choroidal arteria, PCA ( in-between rami of the interpeduncular arterias ) , and the anterior choroidal arteria ( Fig. 11 ) . Followng arterial groups can be identified: [ 23, 42 ] The anteromedial group arises from the PCA The anterolateral group arises from the collicular and posteromedial choroidal arterias or the collicular, posteromedial, and anterior choroidal arterias The sidelong group arises from the collicular arteria or the collicular, posteromedial choroidal, and PCAs. The posterior group arises from the SCA and collicular arterias or the collicular and posteromedial choroidal arterias Figure 11: Arterial Supply of the Midbrain hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=simo7 A ; filename= % 09simo7_c009f012b.gif Beginning: Simon RP, Greenberg DA, Aminoff MJ: Clinical Neurology, 7e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5151404. Midbrain Infarcts These history for 8 % of all infarcts in the posterior circulation. BA disease ( 27 % ) , cardio-embolism ( 23 % ) , and small-artery disease ( 23 % ) were found to be every bit common causes in a survey performed by Bogousslavsky et Al. [ 48 ] Most infarcts are localized in the in-between portion of the mesencephalon, and are characterized by atomic ( bilateral ptosis, bilateral superior rectus failing, or bilateral mydriasis ) or peripheral 3rd nervus engagement ( one-sided adduction/upward/downward paralysis with ptosis and mydriasis ) , with or without hemiparesis. [ 29 ] Infarcts in the upper or lower mesencephalon can be classified harmonizing to their chief characteristics: third-nerve paralysis combined with contralateral unilateral paralysis ( Weber syndrome ) , contralateral ataxic shudder ( Benedikt syndrome ; see Fig. 12 ) , or ataxy and hemiparesis ( Claude syndrome ) . [ 29 ] With occlusions near the beginning of the PCA at the degree of the mesencephalon, optic abnormalcies can include perpendicular regard paralysis, third cranial nerve ( III ) nervus paralysis, internuclear ophthalmoplegia, and perpendicular skew divergence of the eyes, or coma. [ 44 ] Figure 12: Benedikt Syndrome hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=simo7 A ; filename= % 09simo7_c003f012.gif Beginning: Simon RP, Greenberg DA, Aminoff MJ: Clinical Neurology, 7e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5151404. Midbrain Hemorrhage Thalamic bleedings cause several typical optic perturbations. These include: [ 27 ] Deviation of the eyes downward and inward so that they appear to be looking at the olfactory organ Unequal students with absence of light reaction Skew divergence with the oculus opposite the bleeding displaced downward and medially Ipsilateral Horner ‘s syndrome Absence of convergence Paralysis of perpendicular regard Retraction nystagmus Patients may subsequently develop a chronic, contralateral hurting syndrome ( e.g- Dejerine-Roussy syndrome ) . Pons The Ponss is the part of the encephalon prevarication above the myelin oblongata and below the cerebellum and the pit of the 4th ventricle. The Ponss is a wide, horseshoe-shaped mass of transverse nervus fibres that connect the myelin with the cerebellum. It is besides the point of beginning or expiration for four of the cranial nervousnesss ( karyon of the trigeminal, abducents, facial, and acoustic nervousnesss ) that transfer centripetal information and motor urges to and from the facial part and the encephalon. The Ponss besides serves as a tract for nervus fibres linking the intellectual cerebral mantle with the cerebellum. The Ponss controls rousing and regulates respiration. It besides plays a function in slumber. [ 23, 24, 34 ] The Ponss can be divided into a ventral and dorsal portion and the in-between cerebellar peduncles: [ 23, 24, 34 ] Ventral or anterior surface ( Basis Pontis ) It is situated along the midplane of the Ponss and portion of the myelin where the rhaphe karyon lies. Serotonin-containing nerve cells in these karyons project widely to the cerebral mantle and hippocampus, basal ganglia, thalamus, cerebellum, and spinal cord. These cells are of import in commanding the degree of rousing and modulate the sleep-wake rhythm. They besides modulate centripetal input, peculiarly for hurting. Dorsal or posterior surface ( Tegmentum ) The tegmentum of the Ponss is more complex than the base. This dorsal tegmental part is for most a continuance of the reticulate formation of the myelin oblongata, but consists besides of transverse and longitudinal fibres and contains of import grey karyon ( e.g. the karyon of nervus VI and the karyon of nervus VII ) . The upper half of the Ponss harbors the chief centripetal karyon of nervus V. The cardinal tegmental piece of land contains falling fibres from the mesencephalon to the inferior olivary karyon and go uping fibres that run from the brain-stem reticulate formation to the thalamus. The tectospinal piece of land and the median longitudinal fiber bundle are extra constituents of the pontine tegmentum. Middle Cerebellar Peduncle It is the largest of the three cerebellar peduncles. It contains fibres that arise from the contralateral footing pontis and terminal in the cerebellar hemisphere. Further you besides find audile tracts and the trigeminal system ( all right touch, hurting and temperature ) . Blood supply Different arterial short pantss supply blood to the Ponss, including the VAs, AICA, SCA, and BA ( Fig. 13 ) . But it is chiefly supplied by nameless paramedian and circumferential subdivisions of the BA. Following arterial groups can be identified: [ 23, 42 ] The anteromedial group and anterolateral group arises from the pontine The sidelong group arises from the VA and AICA ( superior and posterior rami of the sidelong medullary pit ) , the pontine arterias, or the SCA The buttocks group merely exists in the upper portion of the Ponss and arises from the medial and sidelong subdivisions of the SCA Figure 13: Arterial Supply of the Pons hypertext transfer protocol: //www.accessmedicine.com/loadBinary.aspx? name=simo7 A ; filename= % 09simo7_c009f012c.gif Beginning: Simon RP, Greenberg DA, Aminoff MJ: Clinical Neurology, 7e: hypertext transfer protocol: //www.accessmedicine.com/content.aspx? aID=5151404. Pontine infarcts In a survey performed by Bogousslavsky, pontine infarcts accounted for 15 % of the infarcts in the posterior circulation. Further, BA subdivision disease was the most common cause of shot ( 44 % ) and was associated with big ventral infarcts with terrible clinical characteristics. [ 48 ] Small arteria disease ( 25 % ) was normally associated with little ventral or tegmental infarcts and quickly bettering lacunar syndromes. [ 49 ] Pontine infarcts are classified into four chief groups: [ 44 ] Ventromedial pontine infarcts: associated with moderate to terrible hemiparesis, either pure motor hemiparesis or accompanied by atactic hemiparesis. Ventrolateral infarcts: frequently present as a mild hemiparesis, sometimes associated with atactic hemiparesis or pure motor hemiparesis. Some patients may demo mild marks of tegmental engagement, such as optic abnormalcies, dizziness, and centripetal loss ( sensorimotor shot ) . Tegmental pontine infarcts: they frequently present as dizziness, double vision, oculus motion perturbations, cranial nervus paralysiss, truncal and appendages centripetal loss, and mild motor shortages. Bilateral ventrotegmental infarcts: they are associated with acute pseudobulbar paralysis and uni- or bilateral sensorimotor disfunction. Bilateral big ventral infarcts may do the locked-in syndrome, characterized by tetraplegia, facial diplegia, guttural paralysis, and horizontal regard paralysis with normal consciousness, the patient merely being able to pass on utilizing a codification affecting eye blink and traveling the eyes up and down. Pontine Bleeding Pontine bleeding is basically restricted to hypertensive patients and is the least common of the hypertensive intracerebral bleedings.

Cybele Essays - Cybele, Attis, Galli, Phrygia, Ma, Rosalia

Cybele Cybele, officially known as Mater Deum Magna Idea (Great Idean Mother of the Gods). The Great Mother was especially prominent in the art of the empire. She usually appears with a mural crown and veil, seated on a throne or in a chariot, and accompanied by two lions. Cybele was the Phrygian form of the nature deity of all Asia Minor, she was a universal mother, parent not only of the gods but also human beings and beasts. She was called the Mountain Mother, and special emphasis was placed on her maternity over wild nature; this was manifested by the orgiastic character of her worship. Her mythical attendants, the Corybantes were wild, half-demonic beings. Her priests, the galli, castrated themselves on entering her service. The self-mutilation was justified by the myth that her lover, the fertility god Attis, had emasculated himself under a pine tree, where he bled to death. At Cybele's annual festival (March 15-27), a pine tree was cut and brought to her shrine, where it was honoured as a god and adorned with violets considered to have sprung from the blood of Attis. On March 24, the "Day of Blood," her chief priest, the archigallus, drew blood from his arms and offered it to her to the music of cymbals, drums, and flutes, while the lower clergy whirled madly and slashed themselves to bespatter the alter and the sacred pine with their blood.

Essay about Beauty, the True Beast

Essay about Beauty, the True Beast Essay about Beauty, the True Beast Beauty, the True Beast Beauty is in the eyes of the beholder. As such, beauty is not so easy to define. There are many definitions of beauty based on shape, size, age or even color, as beauty can describe inanimate objects, sounds, or just plain sights such as landscapes as well. Because art comes in many different forms, it is hard to classify any one person or thing as beautiful, as it truly is up each individual person to decide whether or not beauty is present. Any usage of art can bring a form of emotion to the recipient. The emotions felt are a formed by the beauty of the art itself. A canvas has no limits, and any strokes of a paint brush could be described as beautiful, in one’s eyes. A picture of a sunset over the horizon of a lake on a warm crisp summer evening, a homeless woman shielding her child from the tear gas of an oppressive government officer, or something as simple as a dog rolling in the grass can create an aesthetic feeling that some would call beauty. Seeing as how music is a form of art as well, it is not surprising that the voice of an artist belting out the notes of an emotionally driven song can bring out the tears in the listener. Or the familiar groove of a bass line unconsciously forcing a dancer to move their body, while the guitar solo brings a feeling of hopefulness with its arrangements of notes. Even abstract ideas of art can be considered beautiful. A string of events, whether it be a life itself can b e beautiful, or the life of another can be just as artistic and beautiful. Even fictional lives can be beautiful as well. Plots in stories, the thoughts of characters, their outlooks on lives, or even the personalities given to them can be just as artistic, and bring a longing feeling to them. Art in itself can invoke emotion, and make the viewers or listeners feel an overwhelming sense of true beauty radiating from the piece of art. Besides art, many find beauty in other human beings. In the United States for example, most would portray women like Mila Kunis, or Emma Stone as the ideal of beauty. They are slim, curvy, well dressed, and famous. However, the media is the one to credit the public’s belief that this is true beauty. Hollywood creates fantasy worlds in which men fall head over heels for women with â€Å"these† ideal physical traits, and create a false image in their viewer’s minds that is more toxic than most like to admit. Not all women have to appear like Megan Fox to be considered beautiful though. Most times, you find true beauty in the one you love. They don’t need make-up, money, clothes, fame, or the lifestyle of the rich and famous in order to cast a spell of love on somebody, just their pure inner beauty. Sometimes, just one’s personality, or the way that they treat you can be beautiful. To trump an old clichà ©, true beauty is NOT skin deep. In some Africa n cultures, beauty is portrayed in a different way. For instance, the day

Week 5 Assignment Example | Topics and Well Written Essays - 250 words

Week 5 - Assignment Example such as there is no positive outcome of resolving the conflict, it is too trivial, disruption would prove to be very costly, etc mangers tend to use the avoiding style of conflict management (Schyns & Hansbrough, 2010). Hence, it is first important to understand why the manager is avoiding conflict before confronting them. With the exception of the above two cases, an employee must confront the manager if a conflict is being avoided. It is very important for an employee to trust and believe in his or her manager. It is only when an employee trusts the manger to act in the best interest of the employee that he or she can dedicate completely and work for the manager. In the absence, of this trust an employee will not only lose confidence but also be de-motivated. This will affect both the performance of the employee as well as the overall output of the team. This attitude of the manager to avoid conflicts can disrupt the dynamics of a group as employees do not feel recognised or rewarded with respect to the work they do in comparison with other employees. This can further escalate the conflicts in a group. Also, the feedback given by a conflict avoiding manager can be very diplomatic and does not serve the purpose of a feedback. Employees need to have a clear understanding of where they stand in the workplace and how they can improve. This cannot be accomplished with a diplomatic feedback. Therefore, it is important that an employee confronts a conflict avoiding
