MEDICAL PHYSIOLOGY

Detailed explanation-1: -Skeletal muscles comprise 30 to 40% of your total body mass. They’re the muscles that connect to your bones and allow you to perform a wide range of movements and functions.

Detailed explanation-2: -A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.

Detailed explanation-3: -Human skeletal muscle is composed of a heterogenous collection of muscle fiber types. This range of muscle fiber types allows for the wide variety of capabilities that human muscles display. The three types of muscle fibres are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG).

Detailed explanation-4: -Skeletal muscle fibers are broadly classified as “slow-twitch” (type 1) and “fast-twitch” (type 2).

Detailed explanation-5: -Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control.
