Myofibrils account for roughly 80% of cellular volume, and are the contractile elements of the muscle cell. Myofibrils consist of repeating units called sarcomeres (the contractile unit of the myofibril), which have overlapping myofilaments connected to Z discs at either end of the sarcomere.
Like skeletal muscle, the SARCOMERE is the contractile unit of the myocardial cell. It contains myosin and actin filaments as well as troponin and tropomysin. Shortening of sarcomeres causes contraction by the sliding filament model already described.
