Anatomy And Physiology Quizzes & Trivia

The autonomic nervous system is the part of the nervous system that regulates involuntary functions. The contraction of both smooth muscle and cardiac muscle is controlled by motor neurons of the autonomic system. See what else you understood about the chapter through the quiz below.
