The word aneurysm comes from the latin word aneurysma, which means dilation. An aneurysm is an abnormal local dilation in the wall of a blood vessel, usually an artery. It can be caused by a defect, a disease, or an injury. A cerebral aneurysm is an abnormal focal dilation of an artery located in the brain that results from a weakening of the inner muscular layer called the intima of a blood vessel wall (Brisman, 2014). The vessel develops a blister-like dilation that becomes thin and may rupture
(Brain Aneurysm Foundation n.d.). In order to allow the blood to flow properly, the artery walls are composed of both a muscular and an elastic layer. Sometimes, a weak spot in the walls of these arteries occur due to disease, birth defects, or injury, particularly in areas where the arteries branch out. The thin spot of the artery wall gradually becomes weaker from the constant pressure of pumping blood, forming a cerebral aneurysm (Brain Aneurysm 2016). The most common form of aneurysm, a saccular
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
It took me eighteen years to appreciate the profound impact my grandmother had on my life. She was the type of that always had her words of wisdom to pass on to her grandchildren, and the kind heart who donated her time to those who needed it. Being able to grow and learn with such a strong role model I became more like her each day. I started to use her words of wisdom in my daily life, and I remembered the importance of making time for those in need, both friends and strangers. My grandmothers
diagnosis, treatment and follow-up of abdominal aortic aneurysms (AAA). It shall discuss the current AAA screening programme being implemented across the United Kingdom to include the use of Ultrasound and Computed Tomography (CT) as imaging modalities in the demonstration of AAAs. Both the advantages and disadvantages of the modalities used during the diagnosis and treatment of AAA will be shown. Irwin and Rippe (2007, p382) define an aneurysm as; “a segment of the aortic lumen whose diameter exceeds
Lateralization of Function in Cerebral Hemispheres One of the major goals of neuroscience is to be able to understand the relationships between the structures of the nervous system and a persons outward behavior. Often times it is difficult or unethical to directly study the nervous system during a behavior and indirect methods must be used instead. One example of such an indirect method is using a subjects preferred hand to predict which of the two Cerebral Hemispheres is dominant. The are
The cardiovascular system is the most important system in our body. This system is what keeps us alive. Beating on average 30 billion times a year, our heart is never able to stop and take a break. With every beat of our heart, the cardiovascular system moves blood, gases, nutrients, and hormones throughout the intricate vasculature of our bodies. An adult body contains over 60,000 miles of vessels, which can wrap around the world two and a half times. The vessel branching off of the heart is
Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke. Each year alone about 150,000 people in America die from a stroke or are seriously disabled. Stroke is
not being processed for some reason. There are two types of achromatopsia, one is congenital and the other can be caused by brain damage, called cerebral achromatopsia (3). There are also varying degrees of achromatopsia, with some sufferers being able to distinguish some color and others absolutely none. I will focus on the congenital version since cerebral achromatopsia varies in its symptoms and cause quite a bit, as well as being much more rare and so fewer cases have been studied. Congenital color
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

injury to the brain can cause serious consequences in a person which includes paralysis, comatose, and even death. What is brain hemorrhage? One of the common problems that our brain can develop is known as a brain hemorrhage. Brain hemorrhage or cerebral hemorrhage refers to the condition wherein there is bleeding in the brain. This bleeding can occur anywhere inside the skull which includes the area within the brain,
Definition An AAA (abdominal aortic aneurysm) is defined as enlargement of at least 3 cm of the abdominal aorta. The majority of abdominal aortic aneurysms begins below the renal arteries and ends above the iliac arteries. The exact cause of (AAAs) is unknown. However, it is thought to be due to a degenerative process of the abdominal aorta caused by atherosclerosis. Artherosclerosis represents a response to vessel wall injury caused by inflammation, genetically regulated defects in collagen
that are out there, to be able to understand what it was exactly, that I was reading. But with a little study and research I found that this is a precise science that is still largely full of mysteries. The study of hemispheric asymmetry with in the cerebral cortex had long been a fascination with the human race. The ancient Aztec cultures used to perform a type of brain surgery on humans. This is evident from the human remains that we find with incisions and piece's missing of the skull. Whether or
most affected. Changes occur in the cerebral cortex (which is how the frontal lobe is affected.) Pick's disease affects the temporal lobes of the brain in 25%, frontal lobes in 25% and both frontal and temporal lobes in 50% of cases (1). Damage to the frontal lobes leads to alterations in personality and behavior, changes in the way a person feels and expresses emotion, and loss of judgment. On a microscopic level, there is severe neuron damage in the cerebral cortex. The brain cells in these areas
and more important and imperative due to the fact that the overall population seems to becoming more and more emotionally fragile and more subject to several cerebral ills such as depression, anxiety, hysteria, and clinical insanity. A good question to ask is whether or not the overall population seems to be suffering more mental and cerebral ills, or that it is merely a result of more cases being reported and more statistics calculated. But if it is true that the number of people suffering from
In definition, the words Cerebral Palsy are used to describe a medical condition that affects control of the muscles. Cerebral means anything in the head, and palsy refers to anything wrong with control of the muscles or joints in the body. If someone has cerebral palsy, it means that because of an injury to their brain (that's the cerebral part), they are not able to use some of the muscles in their body in the normal way (that's the palsy part). Children who have cerebral palsy, or CP, may not be
There are things in life which none of us can control, in my life there have been many such things. In trying to write this essay I have a difficult time trying to decide what I am going to write about. I have many ideas running through my head,and I am trying to decide what makes me who I am, what makes me special. Soren Kierkegaard said, "Life can only be understood backwards, but must be lived forwards." I have a difficult time understanding my life even as I look back, I am unsure of why
the things I am dealing with when trying to decide whether or not to put my son in a group home. My son is nine years old and suffers from Autism, Cerebral Palsy, and mental retardation.He was born prematurely and critically ill. Though odds were very much against him, he made it. A year later, after his first MRI, we first heard the words Cerebral Palsy. By the age of two I knew he was Autistic but we could not get a diagnosis until he was seven. He was put on medication to help his self-abusive
patterns dependent on the simultaneously activity of neurons. This essay deals primarily with neurons from the optical sensory system. The outer ridge of the brain, known as the cerebral cortex begins the analysis of sensory messages. (1) Nevertheless, visual perception is possibly more widespread than one area of the cerebral cortex and like ly over various subcortical structures and number of different systems as well. (2) One of the many ways for the "perception process" to begin, is vision. Vision
