The Neuromuscles junction can have fiber in them. The fiber can also be the world Neuromuscles junction.

1.Action potential arrives at axon terminal
2.Calcium ions enter axon terminal
3.Synaptic vesicles fuse to membrane of axon terminal
4.Acetylcholine is released into synaptic cleft
5.Acetylcholine binds to receptor sites on motor end plate
6.Motor end plate becomes depolarized
7.Action potential is initiated on sarcolemma
8.Action potential propagates along sarcolemma and down T tubules
9.Calcium ions are released from terminal cisternae
10.Muscle cell contracts
