MUSCLE PHYSIOLOGY

Detailed explanation-1: -Skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control.

Detailed explanation-2: -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-3: -A voluntary muscle is a muscle that you choose to move, like those in the arms and legs, as opposed to the ones that move automatically, like the heart. Muscle is the tissue in animals that produces movement or motion. Voluntary means done out of free will or by choice.
