Like skeletal muscle tissue, it is striated (the muscle fibers contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers). Unlike skeletal muscle tissue, its contraction is usually not under conscious control (involuntary).

 Smooth muscle is found in the walls of all the hollow organs of the body (except the heart). Its contraction reduces the size of these structures.
