Place the events in chronological order as they relate to a muscle contraction. Calcium is released from the sarcoplasmic reticulum. Myosin heads bind to actin. An action potential arrives at the axon terminal of a motor neuron. Calcium binds to troponin, displacing tropomyosin and exposing myosin head binding sites on actin. Myosin heads undergo power stroke and actin slides over myosin towards M line of sarcomere. Acetylcholine is released at the neuromuscular junction.arrow_forwardHow does the structure of a skeletal muscle cell differ from the structure of other cells?arrow_forward
