Question
Chapter 14, Problem 7WYL
Summary Introduction
To determine:
The differences in way axons are myelinated in the PNS and CNS.
Introduction:
The nervous system is comprised of two components: the central nervous system and the peripheral nervous system. The CNS is composed of the brain along with the spinal cord; whereas, PNS comprises the remaining components of the nervous system.
