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 nerve impulse causes the release of acetylcholine from the motor end plate. This causes the depolarization of the membrane of the adjacent muscle cell. Depolarization trig â¦ gers the release of calcium ions from the sarcoplasmic reticulum inside the muscle cell.t is the firing of a nerve which sends an electrical signal down  the axons of that nerve. The message propagates by the movement of  Sodium (Na) and Potassium (K) ions in â¦ and out of the axon  wall/sheath.
