Summary Introduction

To discuss:

Excitation of a muscle fiber, how a nerve signal leads to a traveling wave of electrical excitation in a muscle fiber.

Introduction:

Excitation – it is a process of contraction coupling in the skeletal muscle is the sequence of events through the nerve fiber stimulates the skeletal muscle, causing its contraction. There is three contractile protein, which is present in the thin filaments namely actin, troponin, and tropomyosin. These contractile proteins of muscle convert the chemical energy into mechanical energy.
