Question
Chapter 15.7, Problem 20WDYL
Summary Introduction
To determine:
How the autonomic tone help in permitting the control of diameter of the blood vessel by sympathetic innervation.
Concept introduction:
Multiple organs are innervated by both the divisions of the ANS (autonomic nervous system); parasympathetic as well as sympathetic. These divisions control the target organs to different degrees.

Students have asked these similar questions
Which branch of the autonomic nervous system innervates blood vessels? Which layer of the blood vessel wall do these nerves innervate? What are the effectors (cells that carry out the response)?
What is the influence of the sympathetic NS when the blood pressure is high?
How can the sympathetic division cause smooth muscle torelax in some organs but contract in others?
