Cholinergic agent are the compound which mimic the action of acetylcholine In general, the word choline refers to the various quaternary ammonium salts containing the N,N,N-trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter acetylcholine and functions with inositol as a basic constituent of lecithin. Choline also prevents fat deposits in the liver and facilitates the movement of fats into cells. The richest nutritional sources of choline are liver, kidney, brain, wheat germ, brewer's yeast, and egg yolk. Neurologically, cholinergic is the abbreviated term referring to acetylcholine (the suffix -ergic means stimulating; abbreviated ACh).

The parasympathetic nervous system, which uses acetylcholine almost exclusively to send its messages, is said to be almost entirely cholinergic. Neuromuscular junctions, preganglionic neurons of the sympathetic nervous system, the basal forebrain, and brain stem complexes are also cholinergic. In addition, the receptor for the merocrine sweat glands are also cholinergic, since acetylcholine is released from postganglionic sympathetic neurons.
