WebThe cross bridge cycle ends when Ca2+ are actively transported back into the sarcoplasmic reticulum. The cycle repeats as long as the binding sites on actin remain exposed, and both Ca2+ and ATP are available. A person dies, and within hours, the skeletal muscles develop a locked contraction known as rigor mortis. WebPlace the boxes in the numbered boxes, 1 through 8, according to the order in which these events occur. 1. Acetylocholine binds ligand-gated sodium channels. 2. sodium ions enter the cell, initiating an action potential 3. an action potential travels down the sarcolemma and T tubules 4.calcium ions are released from the sarcoplasmic reticulum
