Skeletal muscles cover your skeleton, giving your body its shape. They are attached to your skeleton by strong, springy tendons or are directly connected to rough patches of bone. Skeletal muscles are under voluntary control, which means you consciously control what they do.
1. Skeletal muscle: refers to most muscles that are under voluntary control. These are cylindrical and often pretty long (because they are multinucleated), with the nucleus on the edge of the muscle so as to not interfere with contractions. 2.Cardiac muscle: refers to the muscles of the heart (cardiomyocytes).here skeletal muscle is voluntary, cardiac muscle is autorhythmic (beats involuntarily; generates its own action potentials). 3. Smooth muscle: refers to the muscles that are controlled involuntarily by the brain, like those attached to the base of hair follicles or in the walls of the gastro-intestinal tract.
