It is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery

The disabling cerebral tube sickness additionally incorporates an important impact on residual advantages that ends up in the most important economic loss [6]. Though India is rated among the country lacking enough information associated with stroke, a number of the recent

One of them call cerebrovaslar(stroke) Etiology/pathophysiology Many underlying factors can contribute for someone to have a stroke; these including not limited to:artherosclerosis,(harding of the arteries) commonly from fat consummation, heart disease (generally) hypertension(high blood pressure), kidney disease, peripheral vascular disease, and diabetes mellitus. Cerebrovaslar accident is an abnormal condition of the blood vessels of the brain, characterized
The topic assigned to me for the health paper is cerebrovascular disease, which is a stroke. Cerebrovascular is really two words combined. Cerebro is the largest part in the brain and vascular is termed as veins and arteries. From those two terms, one can interpret that this disease has to deal with the blood flow that goes on in the brain. According to the Association of Neurological surgeons, cerebrovascular disease is defined as the any disorder that is in the brain is either permanently or temporarily
Brain Aneurysms What is a brain aneurysm? One could define a brain aneurysm as bulging, weak area in the wall of an artery that supplies blood to the brain. Over time, weak areas in the walls bulge out causing the blood vessel walls to become weaker as the aneurysm grows (Simon). In most human beings, a brain aneurysm can go undetected for years even possibly ones entire life. Some people however are not so lucky, in some instances, the aneurysm can rupture or explode, causing a hemorrhagic stroke
mostly observed in young and middle aged people (Liebskind & O 'Connor,2015). Pathophysiology Both intercerebral hemorrhage and hemorrhagic stroke are terms that can be used interchangeably. When a patient is having a hemorrhagic stroke, bleeding occurs in the brain parenchyma. This is usually caused by leakage from tiny intercerebral arteries which are commonly damaged by hypertension. Other risk factors for hemorrhagic stroke are anticoagulant therapies, aneurysms, cerebral amyloidosis, and cocaine
The purpose of this paper is to analyze the concept of Perfusion. Perfusion refers to the flow of blood through arteries and capillaries delivering oxygen and nutrients to cells and removing cellular waste products. Perfusion is a normal physiologic process that requires the heart to generate adequate cardiac output to transport blood through blood vessels for distribution in the tissues throughout the body. The essential function of the cardiovascular system and pulmonary systems is to provide

William Harvey, a man who was born in Folkestone, England in April of 1578, grew up to be a scientist that began his career researching about the Circulatory System, and how blood was transported throughout the body. The circulatory system is defined as: “an organ system that permits blood to circulate and transport nutrients.” Harvey was known as “the Father of Modern Physiology.” He earned his bachelor’s degree from the University of Cambridge, and his doctorate in medicine in 1602 from the University
Kaplan (2001). Damage affecting this Broca’s area may cause a ‘non fluent’ aphasia, in which comprehension remains relatively intact, however language production is impaired (McCaffrey, 2005). The most well known cause of Broca’s aphasia is a Middle Cerebral Artery (MCA) stroke in the left frontal lobe. John is cognitively aware of what he wants to say, however he is unable find the words he needs to convey his message. Primary signs of the disorder
calcification of the media of muscular arteries; arteriolosclerosis, the hyaline thickening of small arteries and arterioles; and the most common atherosclerosis, the formation of atheromas—a thickening of the arterial wall that is brought upon by cholesterol laden plaque and the amassing of scar tissue. Of the three disorders, atherosclerosis (AS) is the most leading cause of death and morbidity in the Western hemisphere. It often targets the aorta and the coronary and cerebral systems, which in turn makes
An aneurysm is a disease of the arteries which due to a weak spot on a blood vessel, causes an outward bulging or ballooning of the arterial wall. It contributes to more than 25,000 deaths in the United States each year. The pathology of the disease is not well understood and even today there has yet to be a method of predicting a person’s probability of developing one such circumstance. Most un-ruptured aneurysms are incidentally discovered through CT scan or MRI and it has proven to be just as
Dura mater – the substance that covers the brain and the spinal cord • Endosteal layer – resembles the periosteum of bones, provides blood vessels • Meningeal layer – dense, fibrous membrane • Falx cerebri – a large crescent shaped fold that is amid cerebral hemispheres • Tentorium cerebelli – horizontal large crescent crease attached to the internal surface of the occipital bone • Falx cerebelli - a fold that divides the cerebellar hemispheres and is attached internally to the occipital bone and is
the middle layer of heart muscle, and it is surrounded by a fluid filled sac called the pericardium. The heart is split into four parts; some may call it chamber or rooms. These parts are the: right atrium, the left atrium, the right ventricle, and the left ventricle. The chambers are separated by partition walls known as the septum and each has a one-way valve that prevents blood from flowing backwards. These four parts help the heart pump blood throughout the body. The right... ... middle of
Introduction A cerebral arteriovenous malformation (AVM) is an irregular connection of arteries and veins within the brain that has no definite cause; many do not experience symptoms (Mayo Clinic Staff, 2011). However, some patients experience headaches and seizures (Starke et al., 2009). The main risk of an AVM is hemorrhage, and patients with AVMs will always have some risk of hemorrhage (Ogilvy et al., 2001); According to Ogilvy et al (2001), more than 50% of AVMs lead to cerebral hemorrhage.

scientists thought he died in the cold up the mountain, some had doubts, and while studying the remains of the mummy, an anomaly was found inside of it. An arrowhead had been found lodged in his back, close to the heart and deep enough to puncture an artery. As the Huffington Post says “ Clearly, the arrowhead had caused a one-centimeter gash

One study was tested by Shimada, Hamakawa, Ishida, Tamakoshi, Nakashima, and Ishida (2013) to see if physical exercise recovers an impaired memory function in stroke rats. The animals were to middle cerebral artery occlusion for 90 min to induce stroke and were randomly assigned to four groups.
