Expert Solution
Introduction

Muscle contraction takes place upon stimulation. Contraction of a muscle is a mechanical process. During muscle contraction, there are several changes occurring in the muscle. Sliding theory or Ratchet theory or walk-along theory explains how actin filaments slide over the myosin filaments to bring about muscle contraction.
