Nicotinic acetylcholine receptors, or nAChRs, are proteins on neurons that signal when a chemical stimulus causes muscles to contract. On the presynaptic and postsynaptic sides of the neuromuscular junction, as well as in the plasma membranes of some neurons, they are cholinergic receptors that create ligand-gated ion channels. The most extensively researched ionotropic receptors are those for nicotinic acetylcholine. The neurotransmitter acetylcholine (ACh) binds to the nAChR, just like it does with the other type of acetylcholine receptor, the muscarinic acetylcholine receptor (mAChR). Nicotinic receptors can be opened by both acetylcholine and nicotine, hence the name "nicotinic," just as muscarinic receptors are so named because they are also activated by muscarine.
