Ligand-gated Na+ channels are found in the postsynaptic membrane of the neuromuscular junction[1]. After a neurotransmitter (acetylcholine) binds to its receptor the channel opens (undergoes a conformational change) allowing Na+ to enter the motor endplate and K+ to flow out[1][2]. This causes the motor endplate to depolarise. If the end plate potential reaches a high enough potential it will go on to trigger an action potential in the cell[1].
