Cardiac muscle also demonstrates striations, the alternating pattern of dark A bands and light I bands attributed to the precise arrangement of the myofilaments and fibrils that are organized in sarcomeres along the length of the cell (Figure 19.2.1a). These contractile elements are virtually identical to skeletal muscle.Smooth muscle fibers are spindle-shaped (wide in the middle and tapered at both ends, somewhat like a football) and have a single nucleus; they range from about 30 to 200 μm (thousands of times shorter than skeletal muscle fibers), and they produce their own connective tissue, endomysium.Although they do not have striations and sarcomeres, …Skeletal muscles are located throughout the body at the openings of internal tracts to control the movement of various substances.
