MUSCLE PHYSIOLOGY

Detailed explanation-1: -All muscle tissues have four functional properties in common which include excitability, contractility, extensibility, and elasticity.

Detailed explanation-2: -Excitability: Ability of muscle to respond to stimuli. Contractility: Ability of muscle to contract or shorten its size. Extensibility: Ability of muscle to stretch. Elasticity: Ability of muscles to return to original length after stretching.

Detailed explanation-3: -Skeletal muscles are made up of long and cylindrical cells. They are multinucleate (having many nuclei) and unbranched. They are also known as striated muscles because they have alternate dark and light bands. They move as per our will, hence they are categorised as voluntary muscles.
