Skeletal muscle

Skeletal muscles are striated muslces that are under voluntary control of the organism. Making up the large muscles masses, they are attached to the bones of the body and are utilized for locomotion and other movements. They have elongated, cylindrical shape, and are multinucleated. The nuclei of these muscles are located just under the plasma membrane, which vacates the central part of the muscle fiber for myofibrils. This unique ararngement of the nuclei allows for higher efficiency.
