Myelin

(MS). Multiple sclerosis is a lifelong autoimmune disease typically found in young adults. Multiple sclerosis is a degenerative disorder of the myelin sheath. Loss of myelin followed by subsequent lack of neural communication and neuronal death is accepted as the primary cause of disability in MS patients (Dutta 2007). In MS, the oligodendrocytes and myelin sheaths of the central nervous system (CNS) deteriorate and are replaced by hardened scar tissue. To understand how MS affects the nervous…

Multiple Sclerosis causes your body’s immune system to start attacking the protective sheath known as myelin. Myelin is the protective tissue around the nerve…

Myelin sheath insulates nerve fibers. The disease is different for different patients, and can vary not only in the appearance of symptoms but in the rate and progression. More common symptoms include fatigue, paresthesia, muscle stiffness or spasms, tremors, weakness, dizziness, paralysis, and bladder or bowel issues. It is a disease of the central nervous system. Although myelin is present in both the central and peripheral nervous systems, different cells produce the myelin in each system…

galactocerebrosidase, a vital enzyme for myelin metabolism. This disease is one of a group of genetic disorders called the leukodystrophies, which affects the growth of development of the myelin sheath, the fatty substance that insulates and protects the nerves in the brain and spinal cord. The myelin sheath continues to develop after birth, with the growth rate peaking before 18 months of age. The myelin sheath is completely developed when a person is about 20 years old. When the myelin sheath…

Chapter Two Literature Review 2.1 Multiple Sclerosis Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system (CNS) that remains incurable. The disease manifests as a wide range of neurological deficits including cognitive impairment, impaired coordination, visual disturbances, and extremity numbness (Weinshenker et al., 1989). MS affects approximately 400,000 people in the US and 2.5 million worldwide and it is the most common inflammatory neurological disease…

power to drive a person to insanity, but also the possibility of deteriorating a person's physical health. Isolation of a person effects a person's physical health. Study's show that lack of contact with other people reduces the production of myelin. Myelin is a protein that forms the protective sheath that insulates nerve fibers in the…

Goodin and D Bates. In this article, Goodin and Bates defines Multiple Sclerosis as an autoimmune disease, (an inflammatory disorder of the CNS, in which the immune system attacks and eats away the protective covering of the neurons, known as the myelin sheath in the brain and spinal cord, leaving multiple lesions). The damaged neurons cause loss of communication between the brain and the rest of the body over a period of time (Goodin, & Bates, 2009). Multiple sclerosis causes many different…

Coyle’s The Talent Code: Greatness Isn’t Born. Its Grown. Here’s How, the ideas and theories addressed throughout these two chapters have really changed the way I have looked at how I have been taking class. These chapters discussed the theory of myelin and deep practices and how those affect the way in which our brain learns certain things. In dance, at least for many of us, we have spent a long period of our lives redefining our technique.This process not only worked to change the way in which…

because is either no action potential or a full amplitude of action potential. We say that action potential is regenerative since a new action potential is generated at each location along the cell membrane. The saltatory conduction occurs on axons with myelin sheaths and in the Nodes of Ranvier. Each action potential have a refractory period, where at the place the action potential occurs in the cell membrane, there is a brief period of time (about 10ms) where is impossible to make another…

Myelin is a layer of protein and fatty acid that surround nerves and allows them to travel faster. Glial cells are responsible for the formation of myelin. 8. Scleroses is the thickening or hardening of body tissues, and in this case, specifically the brain/spinal cord. This effects nerve transmission because the brain will become…
