Chapter 15, Problem 17RQ
Summary Introduction
To review:
The parasympathetic pathways to the smooth muscle of the eye, bladder, and the small intestine.
Introduction:
The motor division of the autonomous nervous system has two branches, namely sympathetic and parasympathetic. The parasympathetic branch is responsible for routine body functions and the sympathetic branch is activated in response to extra
