One of the different stroke is the lateral medulla syndrome. Most of the time it gets misdiagnosed a 50-year-old man who is a non-smoker, non-hypersensitive, non-diabetic showed the history of abrupt commencement of discord of the gait, dysarthria and dysphagia. He is radiologically and clinically diagnosed as a case history of Ischaemic stroke. This subject improved considerably with treatment. Wallenberg is usually caused by obstruction of the cranial articulation of the rear inferior cerebellar artery or the vertebral artery. Embolism or thrombosis may be the cause of the occlusion. The emboli arise from the large vessels or the heart. We can determine Wallenberg syndrome with professional CT/MRI of the cerebrum and clinical eye. It should be controlled with suitable medical care and physical therapy (Saha, et al., 2010)

and Stroke (NINDS), Lateral Medullary Syndrome is a neurological disease is accounted for by obstruction of the posterior inferior cerebellar artery or vertebral artery, eventually resulting in the lateral medulla infarction. Stroke befalling this area of the brainstem frequently occurs to victims usually showing speech and language, perceptual, cognitive, sensory and motor deficits plus different impairments (NINDS, 2017). Anatomical abnormalities Both the right and left VA pass through ventral-lateral part of the brainstem, replenishing the medulla before uniting at the centre to become the basilar artery structure.
The right and left VA to extend off to become respectively right and left posterior inferior cerebellar arteries (PICA) that pass axially and extend to replenish the lateral medulla on their way to the cerebellum.
Anatomies that form the lateral medullar include nucleus solitaries, nucleus ambiguus , descending sympathetic fibres, spinothalamic tract, trigeminal nucleus and tract, vestibular nuclei and inferior cerebellar peduncle. The spinal cord caudally, the pons rostrally, the posterior lateral sulcus, dorsally and anterior lateral sulcus rostrally border and the area of the lateral medulla. As the brain is permeated by inter alia, the PICA, interference of the supply of the vascular in posterior inferior cerebellar artery syndrome can also often lead to some extent of cerebellar function impairment even though it is not regarded an aspect of the illness
(Kim,2003). Major manifestations and chemical findings On account of the condensed arrangement of tracts and nuclei inside that lateral medullar, lateral medullary syndrome due to stroke in the PICA or ventral artery often results in abnormalities in several systems, such as the autonomic, respiratory, bulbar, sensory and vestibule-cerebella systems. Clinical manifestations are different reliant on which specific fibres and nuclei are affected. Specific symptoms associated with the lateral medullary syndrome are bradycardia, Horner’s syndrome, hiccups, diplopia, dysphagia, dysphonia, ataxia, weak gag reflex, hoarseness, hazy vision, problems maintaining sitting position, nausea and vomiting. In connection with these, Horner’s sign, dizziness, gait ataxia and sensory symptoms and signs are usual and take place in almost all lateral medullary syndrome victims. Least familiar but present in about 50% of conditions are a headache, vomiting, limb ataxia, nystagmus, vertigo, hoarseness and dysphagia. Persistent hiccups are hugely associated with the appearance of dysphagia and hoarseness and are probably because of blockade interfering with the nucleus ambiguous (Day et al. 2014). The dysphagia that happens in the critical stage of the lateral medullary syndrome can be especially significant compared to hemispheric stroke patients. These patients frequently need help in eating, even though in single cases of the lateral medulla, betterment is mainly substantial, and it is perceived to take place through a mechanism including the side of the medulla not affected. A broad analysis of 130 victims with MRI-recognized infarctions exclusively on the lateral medulla. It realised that sores near the anterior medulla end are likely to be more toward, and generate facial paresis, dysarthria and dysphagia more often than soreness at the posterior end. Which themselves are expected to be more parallel (Aydogdu, et al. 2001).
Mr. Fix-it is a 59 year old man with a history of alcohol abuse and diabetic hypertension. Mr. Fix-it has been currently experiencing symptoms such as: rambling speech, poor short-term memory, weakness on the left side of his body, neglects both visual and auditory stimuli to his left side, difficulty with rapid visual scanning, difficulty with complex visual, perceptual and constructional tasks, unable to recall nonverbal materials, and mild articulatory problems. The diagnosis for Mr. Fix-it’s problem is most likely a right-hemisphere stroke. A right-hemisphere stroke is occurs when a blood clot blocks a vessel in the brain, or when there is a torn vessel bleeding into the brain. “A right-hemisphere stroke is common in adults who have diabetes and who are over the age of 55”, similar to Mr. Fix-it (Kluwer, 2012). In addition, Mr. Fix-it has a history of alcohol abuse in which it could have also increased his chances of experiencing a right-hemisphere stroke.

The Structure and Functions of the Arteries Arteries are blood vessels that convey blood from the heart to the tissues of the body. The arteries expand and then constrict with each beat of the heart, a rhythmic movement that may be felt as the pulse. Arteries are usually named from the part of the body that they are found, for example; brachial artery found in the arms, metacarpal artery found in the wrist; or from the organ which they supply as the hepatic artery supplies the liver, pulmonary artery brings deoxygenated blood the lungs. The facial artery is the branch of the external carotid artery that passes up over the lower jaw and supplies the superficial portion of the face; the haemorrhoidal arteries are three vessels that supply the lower end of the rectum; the intercostal arteries are the arteries that supply the space between the ribs; the lingual artery is the branch of the external carotid artery that supplies the tongue. The structure of the artery enables it to perform its function more efficiently.
The main aim of this report is to present and analyse the disease called Cerebrovascular Accident popularly known as stroke. This disease affects the cerebrovascular system, which is a part of the cardiovascular system. To achieve this aim this report will firstly talk about the cerebrovascular system with its structure and functions. The main body of this report will look at causes, symptoms, diagnosis, treatments and prevention of stroke.
Despite fear, the risk of arrest, and the risk of dying for helping other people Raoul Wallenberg saved upwards of a hundred thousand Jewish lives from Nazis in Budapest, Hungary, earning the title “Angel of Budapest”. Wallenberg’s selfless actions defined him as an individual, not his noble, wealthy family’s actions. Without the work of Raoul Wallenberg about one hundred thousand lives would have ended in the Holocaust.

Stroke occurs when the blood supply to the brain is blocked or condensed. Blood works to transport oxygen and other beneficial substances to the body’s cells and organs, as well as the brain. There are two main types of strokes that are known as Ischemic strokes and Hemorrhagic strokes. When the blood vessels that provides for the brain becomes congested, is it referred to as ischemic stroke, the most common stroke within adults. Blood clots, a cluster of blood that sticks together, are the cause of Ischemic strokes. Ischemic strokes also takes place when arteries become backed up with plague, leaving less blood to flow. Plague is cholesterol, calcium and fibrous and connective tissue that sticks to the walls of blood vessels. Ischemic strokes eternally damage the brain and cause a person's body to no longer function habitually.Some risk factors that may increase stroke are high cholesterol, diabetes, high blood pressure, and obesity. Some stroke factors are also due to old age or having a family that has a history of strokes. Men are more likely to have a stroke but the most st...
The most common types of topographical types are diplegia, hemiplegia, double hemiplegia, and quadriplegia. The basal ganglia are part of the extrapyramidal system and work in conjunction with the motor cortex in providing movement and serve as the relay center. Damage to this area results in Athetoid Cerebral Palsy, the second most common form of cerebral palsy. Involuntary, purposeless movements, particularly in the arms, hands, and facial muscles, characterize athetosis. In addition, the individual can become “stuck” in abnormal positions or postures and require specific positioning to maintain normal tone and movement.
Jonathan Juste 4/21/14 Hum. Bio Analysis of Angelman Syndrome In 1965 , Dr. Harry Angelman, an English physician, first described three children with characteristics now known as the Angelman syndrome. Angelman syndrome is a neuro-genetic disorder that is usually diagnosed at a very young age, and it happens within 1 in every 15,000 births.
Dementia is a significant health issue in Australia (Australian Institute of Health and Welfare 2012) (AIHW 2012). Whilst Dementia primarily affects older members of the community, it can also affect young people and has a significant influence on overall health and quality of life (AIHW 2012). The type of Dementia is a determinant in the severity and development of symptoms in individuals (Department of Health 2013) (DoH, 2013). The gradual, progressive and irreversible nature of Dementia has a considerable social and physical impact not only on the individual, but also on family and friends.
Epilepsy, also known as “seizure disorder,” or “seizure attack,” is the fourth most common neurological disorder known to mankind, affecting an estimated 2.3 million adults and 467,711 children in the United States. Unfortunately this disorder is becoming far more common and widespread worldwide. This staggering number of cases of people suffering from Epilepsy also involves an average growth rate of 150,000 new cases each year in the United States alone. Generally, many of the people who develop who are a part of the new are mainly either young children or older adults. Your brain communicates through chemical and electrical signals that are all specialized for specific tasks. However, through the process of communication, chemical messengers, also known as neurotransmitters can suddenly fail, resulting in what is known as a seizure attack. Epilepsy occurs when a few too many brain cells become excited, or activated simultaneously, so that the brain cannot function properly and to it’s highest potential. Epilepsy is characterized when there is an abnormal imbalance in the chemical activity of the brain, leading to a disruption in the electrical activity of the brain. This disruption specifically occurs in the central nervous system (CNS), which is the part of the nervous system that contains the brain and spinal cord. This causes an interruption in communication between presynaptic neurons and postsynaptic neurons; between the axon of one neuron, the message sender and the dendrite of another neuron, the message recipient. Consequently, the effects that epileptic seizures may induce may range anywhere from mild to severe, life-threatening ramifications and complications. There are many different types of seizures associa...
The platysma was reflected along with the skin, leaving the sternocleidomastoid muscle. The neck was observed to be divided into two separate main triangles: the anterior and posterior. The anomaly was found during the dissection of the anterior triangle, specifically during the dissection of the carotid triangle. The carotid sheath was isolated lateral to the superior belly of omohyoid and medial to sternocleidomastoid. The carotid sheath was opened using blunt dissection and the contents, the internal jugular vein and common carotid artery, were observed. This process was repeated bilaterally and both right and left appeared normal. When tracing the course of the right common carotid artery, the brachiocephalic trunk was noticeably absent. Instead, the aorta in this particular cadaver had 4 branches originating from the arch. From right to left, the branches are as follows: right common carotid artery, left subclavian artery, left common carotid artery and common carotid artery. The right common carotid artery in its path towards the neck crosses the trachea anteriorly and obliquely close to the thyroid and cricoid cartilage. The right subclavian artery originates from the arch of the aorta and passes retroesophageal towards the right upper extremity. While both right sided arteries presented with an atypical path from the aorta, in the neck
Stroke is a serious medical condition that affects people of all ages specifically older adults. People suffer from a stroke when there is decreased blood flow to the brain. Blood supply decreases due to a blockage or a rupture of a blood vessel which then leads to brain tissues dying. The two types of stroke are ischemic stroke and hemorrhagic stroke. An ischemic stroke is caused by a blood clot blocking the artery that brings oxygenated blood to the brain. On the other hand, a hemorrhagic stroke is when an artery in the brain leaks or ruptures (“About Stroke,” 2013). According to the Centers for Disease Control and Prevention (CDC), “Stroke is the fourth leading cause of death in the United States and is a major cause of adult disability” (“About Stroke,” 2013). Stroke causes a number of disabilities and also leads to decreased mobility in over half of the victims that are 65 and older. The CDC lists several risk factors of stroke such as heredity, age, gender and ethnicity as well as medical conditions such as high blood pressure, high cholesterol, diabetes and excessive weight gain that in...
