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.
Acetylcholine released by the motor neuron at the neuromuscular junction changes the permeability of the cell membrane at the motor end plate.The permeability change allows t â¦ he influx of positive charge, which triggers an action potential.cetylcholine released by the motor neuron at the neuromuscular junction changes the permeability of the cell membrane at the motor end plate.
