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 presence of an enzyme called acetylcholinesterase that degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction.Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction.Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.hus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
