Edmé Félix Alfred Vulpian
Edmé Félix Alfred Vulpian (5 January 1826 – 18 May 1887) was a French physician and neurologist. He was the co-discoverer of Vulpian-Bernhardt spinal muscular atrophy and the Vulpian-Heidenhain-Sherrington phenomenon. Vulpian was born in Paris, France, in 1826. Among other noted discoveries and experiments, Vulpian discovered adrenaline in the adrenal medulla The adrenal medulla () is the inner part of the adrenal gland. It is located at the center of the gland, being surrounded by the adrenal cortex. It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecho ....

Adrenal Medulla
The adrenal medulla () is the inner part of the adrenal gland. It is located at the center of the gland, being surrounded by the adrenal cortex. It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines, including epinephrine (adrenaline), norepinephrine (noradrenaline), and a small amount of dopamine, in response to stimulation by sympathetic preganglionic neurons. Structure The adrenal medulla consists of irregularly shaped cells grouped around blood vessels. These cells are intimately connected with the sympathetic division of the autonomic nervous system (ANS). These adrenal medullary cells are modified postganglionic neurons, and preganglionic autonomic nerve fibers lead to them directly from the central nervous system. The adrenal medulla affects energy availability, heart rate, and basal metabolic rate. Recent research indicates that the adrenal medulla may receive input from higher-order cognitive centers in the prefron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joseph Jules Dejerine
Joseph Jules Dejerine (3 August 1849 – 26 February 1917) was a French neurologist. Early life and education Dejerine was born to French parents in Geneva, Switzerland, where his father was a carriage proprietor. During the Franco-Prussian War (1870) Dejerine worked as a volunteer in a Geneva Hospital and in the spring of 1871 decided to pursue his medicine studies in Paris. In France, he was introduced to and subsequently became a pupil of Alfred Vulpian, a notable neurologist. Career In 1877, Dejerine was appointed to the Hôpital Bicêtre, where he organized a pathological laboratory. He became '' professeur agrégé'' in 1886, and he found the opportunity to concentrate his efforts on neurology. He worked at the Hôpital Salpêtrière from 1895, became professor of the history of medicine in 1901 and received a senior appointment at the Salpêtrière in 1911 as professor of neurology at the University of Paris, School of Medicine.

Fibrillation
Fibrillation is the rapid, irregular, and unsynchronized contraction of muscle fibers. An important occurrence is with regard to the heart. Cardiology There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. * Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm. In this condition the normal electrical pulses coming from the sinoatrial node are overwhelmed by disorganized electrical impulses usually originating in the roots of the pulmonary veins, leading to irregular conduction of impulses to the ventricles which generate the heartbeat. * Ventricular fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of ventricles. It is a common cause of cardiac arrest and is usually fatal if not reversed by defibrillation. Fibrillation may sometimes b ...

Adrenaline
Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. It plays an essential role in the fight-or-flight response by increasing blood flow to muscles, heart output by acting on the SA node, pupil dilation response, and blood sugar level. It does this by binding to alpha and beta receptors. It is found in many animals, including humans, and some single-celled organisms. It has also been isolated from the plant '' Scoparia dulcis'' found in Northern Vietnam. Medical uses As a medication, it is used to treat several conditions, including allergic reaction anaphylaxis, cardiac arrest, and superficial bleeding. Inhaled adrenaline may be used to improve the symptoms of croup. It may also be used for asthma when other treatments a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
