Summary Introduction

Introduction:

An action potential is an electrical impulse used for passing the signal between the nerve cell and muscle cell. It occurs only when there is a high density of ion channels. The pathway of action potential begins at the axon and trigger zone. Action potential begins always with depolarization, whereas local potential begins with depolarization or hyperpolarization. Action potential has a greater effect of long distance from the origin point as it is self-propagating; signal strength is maintained irrespective of the distance.
