Which of the following is the correct sequence to describe the steps in muscle contraction? 1. tropomyosin blockage is restored with the removal of the calcium and the contraction ends 2. myosin heads attach to actin and detach pulling the actin filaments toward the center of the sarcomere 3. calcium ions bind to troponin which changes shape, removing the blocking action of the tropomyosin 4. nerve impulse reaches the end of an axon and ACh is released and diffuses across the synaptic cleft to attach to ACh receptors on the sarcolemma of the muscle fiber 5. action potential travels along the sarcolemma and down the T tubule into the interior of a muscle fiber triggering calcum ion release from the sarcoplasmic reticulum
