 (ə-sēt′l-kō′lēn′)
n.
A substance, C7H17NO3, that is derived from choline and is released at the ends of nerve fibers in the somatic and parasympathetic nervous systems, where it mediates the transmission of nerve impulses.

acetylcholine

n
(Biochemistry) a chemical substance secreted at the ends of many nerve fibres, esp in the autonomic nervous system, and responsible for the transmission of nervous impulses. Formula: CH3CO2(CH2)2N(CH3)3+
