The transverse striations of skeletal muscle form a characteristic pattern of light and dark bands within which are narrower bands. Smooth muscle is usually arranged in sheets or layers, commonly oriented in different directions. A radial muscle, on the other hand, widens the opening when it contracts. Muscles enable animals and man to perform very important physiological functions, such as movement of the body or its individual parts, blood circulation, respiration, passing of chyme through the digestive organs, maintenance of vascular tonus, and excretion.
