nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
The two types of receptors that bind acetylcholine are nicotinic receptors and muscarinic receptors. Nicotinic receptors are ionotropic receptors found at the neuromuscular junction and in the autonomic ganglia, while muscarinic receptors are G-protein coupled receptors found in various organs like the heart, lungs, and digestive system.
