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.
Best Answer: Many nerves in the human body secrete acetylcholine at their nerve endings. The acetylcholine diffuses accross a gap called a synapse and stimulates the next nerve or a muscle. This action of acetylcholine has to be brief in order for the brain to be able to change it orders to the rest of the body. Therefore acetylcholinesterase causes water to be added to the acetylcholine molecule to break it down into choline and acetic acid.
