MUSCLE PHYSIOLOGY

Detailed explanation-1: -Skeletal muscle: Skeletal muscles are voluntary muscles, meaning you control how and when they move and work. Nerves in your somatic nervous system send signals to make them function. If you reach for a book on a shelf, you’re using skeletal muscles in your neck, arm and shoulder.

Detailed explanation-2: -Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance.

Detailed explanation-3: -They are called voluntary muscles because their action is under the control of the somatic nervous system and their movement can be controlled by us (Eg: Bicep muscles), unlike as in the case of involuntary muscles (Eg: cardiac muscles). The muscle fibers of striated muscles are multinucleated and cylindrical.
