Question
Chapter 18, Problem 9WYL
Summary Introduction
To determine:
The differences between the white and gray rami communicantes based on their structure and function.
Introduction:
The sympathetic division is much more complex than the parasympathetic division. The sympathetic preganglionic neuron originates from the lateral horn of the T1-L2 segments of the spinal cord.
