Detailed explanation-1: -The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle).

Detailed explanation-2: -Skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control.

Detailed explanation-3: -Straited muscle or skeletal muscle is a voluntary muscle, which means that we can actively control its function. It’s attached to the bone and forms a distinct organ of muscle tissue, blood vessels, tendons, and nerves that covers our bones and allows movement.

Detailed explanation-4: -NARRATOR: The nervous system orders the body’s muscles to contract. We can deliberately order the skeletal muscles to contract, which enables us to perform movements. These voluntary movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe.

Detailed explanation-5: -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.
