List the events that occur at the neuromuscular junction

The action potential travels down the axon terminal of the presynaptic cell. This causes the voltage Ca+2 channels to open allowing Ca+2 enters the cell. The Ca+2 ions will then interact with vesciles that contain acetyleonin (ACh) that will undergo excotyosis. The ACh will then be within the synapse and attach itself to the ligand gated Na+1 channels of the post synaptic cell. This causes the gate to open and allow Na to enter the cell. This makes the postsynaptic cell to become depolarized (becoming positive) reestablishing the Action Potential.
