Question
Chapter 14, Problem 7RC
Summary Introduction
To review:
The reason for the faster response time in a monosynaptic reflex than the response time in a polysynaptic reflex.
Introduction:
A reflex action is an automatic and immediate action, which the body generates in response to an external stimulus. It is done by the reflex arc. Reflexes are divided into many categories based on their response, the complexity of circuit, processing, and development. On the basis of the complications in the neural circuit, the reflexes are divided into two: polysynaptic reflex and monosynaptic reflex.
