Plаce the fоllоwing events оf skeletаl muscle contrаction and relaxation in the correct order.1. Ca2+ binds to troponin; tropomyosin moves, exposing the active sites of actin.2. The motor neuron stops releasing ACh, and acetylcholinesterase degrades the ACh in the synaptic cleft.3. Actin and myosin bind, and myosin undergoes a power stroke. ATP detaches actin and myosin, and the cycle repeats, resulting in contraction of the muscle fiber.4. Acetylcholine (ACh) triggers an end-plate potential in the motor end plate.5. The cytosolic concentration of Ca2+ returns to the resting level, the active sites of actin are blocked, and the muscle fiber relaxes.6. An action potential in the sarcolemma travels down the T-tubules.7. Ca2+ are released from the sarcoplasmic reticulum into the cytosol.
