Chapter 14, Problem 7CYR
Summary Introduction
Introduction:
The sympathetic nervous system (SNS) performs two types of functions. They either block the receptor, known as the antagonists, or they activate thereceptor, and are called agonists. There are 5 receptorsassociated with SNS, i.e.,α1, α2, β1,β2, andβ3.
