Summary Introduction

To discuss:

The basis and the significance of the refractory period that follows an action potential.                  

Introduction:

It is impossible or difficult to trigger the site of a nerve cell to fire again for a short period, during an action potential is called the refractory period. It is classified into the absolute refractory period and a relative refractory period. A refractory period is the typical recovery time. The absolute refractory period relates to depolarization, whereas relative refractory period relates to hyperpolarization.
