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).
Upon completion of this section, you will be able to: 1  Describe the key ways that muscarinic receptors differ from nicotinic receptors. 2  Describe where muscarinic receptors are found. 3  Identify the key physiological effects that result from stimulation of muscarinic receptors by excessive amounts of acetylcholine.uscarinic, G-Protein Mediated Receptors. The key response differences between muscarinic and nicotinic receptors is that the response of muscarinic receptors: (Hoffman and Taylor 2001). 1  Is slower. 2  May be excitatory or inhibitory.
