neurotransmitter
Chemical that diffuses across a synapse, and thus transmits impulses between nerve cells or between nerve cells and effector organs (for example, muscles). Common neurotransmitters are the amino acids glutamate and GABA (gamma-amino butyric acid), as well as noradrenaline (which also acts as a hormone) and acetylcholine, the latter being most frequent at junctions between nerve and muscle. Nearly 50 different neurotransmitters have been identified.
