Cholinergics (agonists) and the parasympathetic nervous system: direct-acting cholinergics it works at the receptor, mimics effects of endogenous ligand, bind to muscarinic cholinergic receptors, bethanechol- muscarinic cholinergic agonist, stimulates smooth muscle contraction via m3 receptors coupled to. Gq proteins: we want the gi system to wake up!
