Question
Chapter 12.3, Problem 2AYLO
Summary Introduction
To discuss:
The structure of the myelin sheath as well as how CNS and PNS produce it.
Introduction:
The myelin sheath is an outgrowth of neuroglia, a fatty substance that is present in the axon of some neurons. It is essential for the proper working of the nervous system. The myelin sheath is an outer covering of axon that protects the neuron and increases the speed of signal transmission.
