Electrotonic flow of current from terminal to endplate allows the muscle to produce an end plate potential

Ca⁺⁺ is released inside of the muscle fibre because of Na⁺ and K⁺ entry

Vesicles fuse with the membrane and ACh is released into the synaptic cleft

Vesicles fuse with the terminal membrane and ACh esterease is released into the synaptic cleft

Ca⁺⁺ enters the terminal membrane allowing ACh receptors to fuse with the membrane
