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 is released at the neuromuscular junction and binds to a nicotinic receptor, causing an action potential to fire down the T tubules. The voltage change from this â¦ is sensed by the Sarcoplasmic Reticulum which then releases Ca2+ ions into the cytosol.
