WebLike the coating around an electrical wire, myelin insulates and protects the axon and helps speed nerve transmission. Myelin is present in the central nervous system (CNS) and peripheral nervous system (PNS); however only the central nervous system is affected by MS. CNS myelin is produced by special cells called oligodendrocytes.

WebMyelin is essential to the conduction of nerve impulses in the brain and spinal cord, and myelin loss is a key pathophysiological component of neurological injury and disease, … WebThe purpose of myelin sheath is to assist with the propagation of nerve impulses. It functions in this capacity by insulating the internal cytosol from the extracellular fluid. When the nodes of Ranvier open in response to stimulus, the resulting depolarization can only be transmitted along the axon since the myelin sheath is insulating.
