WebMyelin. Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. If myelin is damaged, these impulses slow down. This can cause diseases ... 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, …
