Summary Introduction

Introduction:

The cells of skeletal muscles are electrically excitable as there is an unequal distribution of ions near their plasma membrane. This separation of charges is termed an electrical gradient or electrical potential. The potential difference across the plasma membrane is called membrane potential. The membrane potential in the absence of stimulation is called resting membrane potential, whereas a temporary change in membrane potential in the presence of a stimulus is called action potential.
