Neurons that secrete acetylcholine are called "cholinergic". There are two distinct types of receptors for the neurotransmitter, named after the agonists used in their discovery, Nicotinic and Muscarinic. The former is an ionotropic receptor (ion channel) and is the principle receptor located at the neuromuscular junction, while the latter is coupled to [[G proteins]] to mediate ion conductance. | Neurons that secrete acetylcholine are called "cholinergic".
