Question
Chapter 9, Problem 2RA
Summary Introduction
To determine:
The location of parasympathetic ganglia.
Introduction:
Different divisions of the nervous system are associated with the control of different parts of the body. The neural pathway of each division of the nervous system is different in several aspects. The two divisions of the parasympathetic nervous system are associated with the control and coordination of voluntary and involuntary muscles.
