Acetylcholine is the neurotransmitter used at the neuromuscular junction âin other words, it is the chemical that motor neurons of the nervous system release in order to activate muscles.
The neurotransmitter, acetylcholine, once it has diffused into the synapse, binds to the nicotinic acetylcholine receptors, which are found in the motor end plate. These receptors are ligand-gated ion channels, and once acetylcholine has binded to the receptors, it causes the channels to open.
