Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, regulation of contraction, and excitation-contraction coupling. Smooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax.
Control. Smooth muscle and cardiac muscle are both involuntary muscles. Specialized cardiac muscle fibers make up the pacemaker that regulates your heart rate. This pacemaker, in turn, is under the control of the autonomic nervous system, the part of the nervous system that operates below your level of consciousness.ocation. Cardiac muscle forms the myocardium, or muscular wall of the heart. The major blood vessels arising from your heart, such as the aorta, also contain some cardiac muscle. Smooth muscle, on the other hand, is a major component of the walls of all blood vessels.
