-A myelin sheath is a layer of white, fatty material which is wrapped around the axons of many [[neuron]]s found within the body. It acts as an electrical insulator, preventing electrical currents from leaving the axon. It also speeds the process by which impulses travel along the [[neuron]]. In axons which lack myelin sheaths, impulses travel in waves, whereas in myelinated axons, impulses 'hop', moving faster than they otherwise would.

-Myelin sheaths which have been lost or degraded disrupt signals between the [[brain]] and the affected parts of the body, and are a contributing factor to many neurodegenerative diseases, including multiple sclerosis. Myelin sheaths do not regenerate naturally, therefore medical attention is necessary should degradation take place.
