The myelin sheath covering the nerves fibers of the brain and spinal cord is composed of several layers of a fatty substance known as lipoprotein. In addition to acting as a protective covering for the nerves, the myelin sheath also allows rapid conduction of electrical impulses along the nerve fibers. When the myelin >> Read More ...
