Acetylcholine

n. acetic acid ester of choline which is found in the human body and used in certain medications

The chemical compound acetylcholine, often abbreviated as ACh, was the first neurotransmitter to be identified. It is a chemical transmitter in both the peripheral nervous system (PNS) and central nervous system (CNS) in many organisms including humans. Acetylcholine is one of many neurotransmitters in the autonomic nervous system (ANS) and the only neurotransmitter used in the somatic nervous system (SNS). Acetylcholine is the neurotransmitter in all autonomic ganglia.
