Myofibrils are formed by many

WebMyofibrils constitute the contractile system, which consists of four complex proteins: myosin, actin, tropomyosin, and troponin. These four proteins are arranged into a functional unit called a sarcomere (see Fig. 2 ). The sarcomere consists of two overlapping bands called the anisotropic or A band and the isotropic or I band.
