Question
Chapter 12.2, Problem 7AYP
Summary Introduction
To determine:
The parts of a monosynaptic and polysynaptic reflex arc, a reflex, and the way by which reflexes are homeostatic.
Introduction:
The neuronal pathway that regulates a reflex is called the reflex arc. It is the basic operative unit of the nervous system that is able to receive a stimulus and generate a response.
