Best Answer: The Medulla oblongata is the part of your brain that controls basic survival functions. It contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing. 3 years ago, I was diagnosed - hypertension with a reading of 160/100.
By Sally Robertson, BSc. The term demyelination refers to loss of the myelin sheath that surrounds and protects axons in the central nervous system. Demyelination occurs as the result of diseases that damage the myelin sheath or the cells that form it. Diseases that are characterized by this loss of myelin are referred to as demyelinating diseases. The myelin sheath covers and insulates axons, aiding the conduction of electrical signals between nerves.
Demyelination impairs the conduction of signals in the affected nerves, causing impairment in sensation, movement, cognition, or other functions depending on which nerves are involved. Multiple sclerosis is believed to be caused by the bodyâs immune system attacking the myelin coating on the nerves. There are more than 400,000 people in the United States with multiple sclerosis, for which there is no cure. The study is published in The Journal of Neuroscience.
