Striated Muscle - regularly arranged contractile units. A. Skeletal Muscle - long, cylindrical multinucleated cells with peripherally placed nuclei. Contraction is typically quick and vigorous and under voluntary control. Used for locomotion, mastication, and phonation.. The tongue is the strongest muscle in the body (relative to size). There are about 640 skeletal muscles in the human body. It takes twice as long to lose new muscle if you stop working out than it did to gain it..
