WebCardiac muscle contraction occurs via the sliding filament model of contraction, much like skeletal muscle. Once calcium is bound to troponin-C and the conformational change of tropomyosin has occurred, myosin heads can bind to actin. Following this ADP and inorganic phosphate are released from the myosin head so the power stroke can occur.
