Summary of Cholinergic receptors
There are two types of cholinergic receptors: nicotinic receptors and muscarinic receptors. Both receptors are present on the sympathetic and parasympathetic postganglionic fibers, and also on target organs. All are activated by the neurotransmitter acetylcholine. Nicotinic receptors act as transmembrane sodium/potassium channels, while muscarinic receptors need to act through intracellular proteins.
