Progress made in the study of the cellular and molecular function of cholinergic nerve terminals suggests that the textbook schemes need to be extended. Vesicles contained in cholinergic nerve terminals not only store acetylcholine but also ATP and Ca2+ as well as peptides. These substances when co-released by exocytosis may modulate transmission both pre- and postsynaptically.
