SSSSS [86.1K]
1. Action potential reaches the axon terminal and depolarizes it.

2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.

4. Exocytosis of acetylcholine into the synaptic cleft occurs.

5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.

6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
