Summary Introduction

Introduction:

The nervous system of animals is made up of many neurons that innervate the muscle cells so that they can respond to a stimulus. The membrane of a neuron when not conducting electrical impulse exhibits resting membrane potential. In resting condition, the inside of the neuron is negatively charged (about −70 mv or millivolt) as compared to the outside of the neuron. This is due to an unequal distribution of positively charged ions such as sodium and potassium.
