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 electrical signal causes the vesicles to degranualate. Releases the ligand (acetylcholine) (also known as a neurotransmitter) into the synaptic cleft. The ligand then looks for its receptor on the postsynaptic cell. The ligand-receptor interaction is highly specific. The receptors will only bind acetylcholine.
