(a) What is myelin? (b) How does the myelination process differ in the CNS and PNS?© BrainMass Inc. brainmass.com June 3, 2020, 7:38 pm ad1c9bdddf
Myelin is a multilayered lipid and protein covering, wrapped around axons of most mammalian neurons that is produced by neuroglial cells. The entire wrapping is called a myelin sheath. It serves many functions, but essentially acts to increase the speed of nerve impulse conduction through a process called "saltatory conduction."
There are two types of neuroglia that produce myelin sheaths. In the peripheral nervous system, neurolemmocytes (Schwann cells) produce ...
Myelin is described and the myelination process in the CNS and PNS are contrasted.
