WebForce in Smooth Muscle Arises from Ca 2+ Activation of Actin–Myosin Interaction. Smooth muscles contain thick and thin filaments, composed predominantly of myosin and actin, respectively. However, their arrangement is quite different from the striated muscles. The filaments are not organized into sarcomeres, and the ratio of thin to thick ... WebA globular protein present in muscle and in nonmuscle cells that has an ATPase activity; in combination with actin, it forms actomyosin; myosin forms the thick filaments in muscle.
