"網頁The contraction cycle occurs in three stages: excitation−contraction coupling, contraction, and relaxation. Muscle fibers are stimulated by motor neuron axons, which end at muscle fiber end plates or neuromuscular junctions. At an end plate, the axon branches and forms many synaptic boutons. Each synaptic bouton is closely located over a ... " - Steps for muscle contraction in order
