The following: Molecular structure of actin and myosin Function of troponin and tropomyosin in the contraction cycle. Introduction: The skeletal muscles are composed of muscle fibers that contain myofilaments, the actin, and myosin filaments and these filaments help in the contraction of the muscles. The actin and myosin are light and dark bands, respectively that are present in an alternate manner. The sliding of light bands over the dark bands results in the muscle contraction.
