Myelin

Multiple sclerosis (MS) is a chronic inflammatory disease that affects the nerve and nerve fibers of the central nervous system (Ringold, Lynm, & Glass, 2006). It results in the loss and damage of myelin, the insulator of nerve fibers, thus affecting the conduction of nerve signals within the brain and spinal cord. This damage to the central nervous system (CNS) leads to an impairment in sensory, cognitive, and motor functions of the body. The cause of multiple sclerosis is still unknown, however

symptoms, Multiple Sclerosis (MS) and Psoriasis are significantly linked, they are both immune-mediated and can be treated by the same drug: dimethyl fumarate. Multiple Sclerosis is an autoimmune disease in which the body’s immune system attacks the Myelin Sheath that covers a nerve cell in the CNS, thus causing scar tissue called Sclerosis.* Relapsing-Remitting Multiple Sclerosis (RRMS) involves episodes of inflammation called relapses which include: numbness and tingling, fatigue and vision loss (also

In the early 1920’s animal experimentation was crudely developed for testing and evaluating products and medicines. Animals, such as rodents, are injected with certain medicines or fed specific ingredients found in these products. Many results from these testings include pain and suffering for the animal experimented on. I believe that animal experimentation should have restrictions. These experiments can be important in discoveries relating to cures for diseases and other medications, but many animals

conduction velocity depending on where the measurement was taken on the nerve. This could possibly be due certain areas of the nerve being more concentrated with particular fibers (A, B, or C). Each fiber had different diameters and not all had a myelin sheath. These factors greatly influence conduction velocity. From this experiment we moved on to the strength-duration curve in exercise 3. For our nerve, the duration could not be decreased low enough as seen in Figure 3. This is could have been

autoimmune disease that majorly affects the brainand the spinal cord (A.D.A.M. Medical Encyclopedia, 1). The disease affects the central nervous system and thus causes limitations of individuals to carry out various activities. In multiple sclerosis, the myelin sheath that covers nerve cell axon is destroyed causing inflammation (MediResource Inc., 1). Destructionof the membrane leads to slowed conveyance of signals from the spinal cord to the brain, which as a result leads to reduced response to different

Adrenoleukodystrophy (also known as X-linked adrenoleukodystrophy, ALD, X-ALD, adrenomyeloneuropathy, Siemerling-Creutzfeldt disease, or Bronze Schilder disease) is a progressive type of a genetically inherited disease that can cause damage to the myelin sheath, spinal cord and white matter in the central nervous system. When affected with ADL your body cannot break down very long-chain fatty acids (VLCFA), causing high levels of saturated VLCFA’s to build up in the brain, nervous system, adrenal

When you hear someone say “The learning process,” it sounds very boring! I will be telling you about the learning process but in a more interesting concept. There are stages to this process and everyone has to learn but the question is “Do everyone learn the same way?” Have you ever wanted to know how the learning process work! I will be telling you how these processes work. The brain work in stages and there are 6 stages to the learning process. The name of this learning process is “The Natural

Neurons and Skeletal Muscle The human body uses unspecialised sperm cells which come from egg cell from the female or sperm cell form the male (zygote) then they specialise into neuron and skeletal muscle or any other type of cell. The stem cells are the building blocks they go through a various process called stem cells differentiation which allows them to be specialise. • The zygote turns into a morula which is called a totipotent; totipotent is a whole organism which can turn into multiple types

Marco R. Jerez 18 September 2015 Reflection Paper Multiple Sclerosis and Guillain-Barré Syndrome are two autoimmune disorders of the nervous system that occur when the myelin sheath surrounding the axons of a nerve degenerate. Multiple sclerosis (MS) affects the central nervous system while Guillain-Barré Syndrome (GBS) involves the peripheral nervous system.1,2 MS is a gradually regressing disease that usually occurs in one of four ways. The first is relapsing-remitting MS (RRMS)

DISCUSSION Biphasic CAP. For the recording of a biphasic compound action potential, both the positive and negative recording electrodes were used, with the negative recording electrode at position ‘D’ and the positive recording electrode at position ‘E’ (refer to Figure 1). The extracellular bipolar recording takes the difference between what the negative electrode picked up and what the positive electrode picked up. The first, positive deflection of the CAP was caused by the extracellular negative
