Nicotinic acetylcholine receptors, or nAChRs, are cholinergic receptors that form ligand-gated ion channels in the plasma membranes of certain neurons and on the postsynaptic side of the neuromuscular junction . As ionotropic receptors, nAChRs are directly linked to ion channels and do not use second messengers (as metabotropic receptors do).
