Chapter 7, Problem 2MC
Summary Introduction
Introduction:
The brain and the spinal cord are the two major part of the central nervous system (CNS). This system performs a major role in receiving the signals and influencing the various activities performed by the body. Thus, it performs a central role in control and coordination between the brain and the body.
