1, muscarinic receptors are composed of seven transmembrane helical domains connected by three extracellular and three intracellular loops. Initially, on the basis of pharmacological selective affinity to the muscarinic agonist pirenzepine, two subtypes of muscarinic receptors, M 1 R and M 2 R, were described (61).
Muscarinic acetylcholine are also present and distributed throughout the central nervous system, in post-synaptic and pre-synaptic positions. There is also some evidence for postsynaptic receptors on sympathetic neurons allowing the parasympathetic nervous system to inhibit sympathetic effects.heir counterparts are nicotinic acetylcholine receptors (nAChRs), receptor ion channels that are also important in the autonomic nervous system.
