WebSmooth muscle uses actin and myosin filaments for contraction. The mechanism, illustrated in Figure 5-10, differs from that in skeletal muscle. Smooth muscle has tropomyosin but lacks troponin C. Calcium acts through calmodulin to activate myosin light-chain kinase to phosphorylate the myosin heads. This increases myosin ATPase activity.
