Summary Introduction

To review:

The way the excitation and the contraction coupling reactions work.

Introduction:

In the process of muscle contraction, the ion channels, action potential and neuromuscular junction work jointly. When the muscle fibers of the motor unit receive an impulse, a reaction is stimulated between the actin and myosin filament of each sarcomere. Because of this reaction, the contraction starts and the initiation of sliding filament theory takes place.
