WebMyocytes contain thousands of myofibrils. Each Myofibril is composed of numerous sarcomere s, the functional contracile region of a striated muscle. Sarcomeres, in turn, are composed of myofilaments of myosin and actin, which interact using the sliding filament model ( powered by molecular motors) and cross-bridge cycle to contract.
