Myelin

disease that causes irreversible neurodegeneration damage to the CNS (1). MS translates to multiple scars which are caused from the demyelinating disease of the CNS (2). The myelin that surround the axon of neurons are a protective layer called a sheath. The sheath is responsible for…

in which the immune system eats away at the protective myelin coating on the nerves causing communication issues within the brain and body. It’s not contagious, but it effects approximately 2.3 million people around the world, usually between the ages of 20 and 50 years. There are different types of MS and a very broad range and severity of symptoms. The cause of MS isn’t really understood. It is known that the immune system attacks the myelin coating on the nerve fibers in the central nervous…

Multiple Sclerosis is an autoimmune disease that causes a disruption of the myelin sheath that insulates and protects nerve cells in the brain and spine. It is an abnormal response in the body in which the immune system’s T-cells pass from the bloodstream into the nervous system to attack the myelin sheath around nerve cells. Myelin sheath are essential to the body for the nervous system to function appropriately. They are a fatty white substance that encompass a nerve cell to form an…

In chapter 4 of Daniel Coyle’s The Talent Code: Greatness Isn’t Born. Its Grown. Here’s How, Coyle articulates a conversation he had with a teenager, John Crawford, about the concept of deep practice. Crawford described the moment that he truly began deep practicing as “clicking in.” (87). This explanation of the feeling of deep practice resonated with me because I felt that same “clicking in” feeling around mid-term of this semester. In my last paper, one of my goals was to be more conscious in…

MS will have abnormal results from this test. Since there is no known cure, a variety of treatments are available to help slow down the progression of MS. Taking immunosuppressive drugs reduces the body’s defensive immune response that targets the myelin sheath; coupled with physical therapy, the physical symptoms of MS can be drastically reduced.The emotional stress of having MS can be be dealt with via support groups or…

Peroxisomes and Adrenoleukodystrophy Adrenoleukodystrophy, or ALD, is a rare genetic disorder in which the myelin sheath surrounding nerve cells in the brain breaks down, and the adrenal gland progressively loses function.(medical dictionary. Myelin sheaths coat nerves to speed up and strengthen neural impulses. If the myelin malfunctions, many neural messages will not do what they should. ALD primarily affects boys and men. It is extremely rare, only 1 in every 100,000 people are afflicted.…

In MS, there is demyelination (loss of myelin sheaths) in the central nervous system (CNS), leading to scarring and/or plaque formation and ultimately resulting in the loss of axons. Autoreactive B and T cells attack myelin autoantigens and cause inflammation in white matter in the CNS (McCance & Huether, 2014). B cells produce autoantibodies, secrete inflammatory cytokines, activate…

in the matured CNS involves a secretion of special chemical molecules called neurotransmitters. Neuroglia provide a variety of functions for brain tissue and support the metabolic and signaling functions of the neurons. Certain types of neuroglia, myelin, serve as an insulation around axons. 4. Neuroglia function depends on the specific type of neuroglia, but they are not sensitive the stimuli and do not generate or conduct nerve impulses. A. Astrocytes: is a star shaped cell that has many…

impairments, weakening of muscles, numb or prickling sensations, worsening of balance and coordination, and even memory problems (Multiple Sclerosis). This disorder arises from the breakdown of myelin, which is needed for proper nerve functioning. It is an autoimmune disorder because the body attacks its own myelin sheath, causing these difficulties. This disorder affects around 400,000 Americans, and the deteriorating symptoms are continuous with no current cure (Taylor 2012). In order to help…

The brain, being the most complex organ of the body, controls every action and thought. It is divided into various functional units formed from brain cells that work together to respond to particular stimuli. The brain cells connect with other cells of the body to create communication routes for brain signals. As such, scientists are working to understand the complex organization of the brain with the help of tools that can tag and trace the circuits of the brain as well as finding out how…
