The correct sequence starts with the release of acetylcholine (5), which leads to the depolarization of T tubules (4). This depolarization triggers the release of calcium (2), which binds to troponin. ATP is then split (6), providing the energy for the sliding of filaments (3), which ultimately causes the muscle to shorten (1).
