Expert Solution

Introduction:

Excitability is defined as the ability of the living tissue to give response to a stimulus. In all the tissues, the initial response to a stimulus is electrical activity in the form of an action potential. This electrical activity is followed by mechanical activity in the form of contraction, secretion, etc.

Action potential in a cardiac muscle is different from that of other muscles and nervous tissues.
