Question 28 4 pts Once the action potential occurs in the sarcolemma, it spreads moving down the T-tubules. What next? What is the correct order of events which result in skeletal muscle contraction? (4 points) a. Once the muscle cell action potential is initiated then calcium ions are released from the sarcoplasmic reticulum. These calcium ions bind to troponin. With this binding, tropomyosin is pulled away from the active sites on actin. Myosin can bind with actin forming a cross...
