            ohm
answer
        tells the resistance in the wire to the flow of electricity
question
            ACh
answer
        endogenous NT (not a good drug because rapidly metabolized); clinical use = produce complete miosis in eye surgery
question
            Methacholine
answer
        muscarinic selective, slightly longer duration of action; clinical use = bronchial airway hypersensitivity testing (diagnostic tool)
question
            Carbachol
answer
        carbamic acid derivative of ACh designed for longer duration of action (resists hydrolysis once bound to AChE); used in the eye to target the desired tissue, but not nicotinic/muscarinic selective; clinical use = produce complete miosis in eye surgery
question
            Bethanechol
answer
        added methyl to carbachol makes bethanechol; long-acting (resists hydrolysis) and selective for muscarinic receptors; bladder and GI hypotonia
question
            Pilocarpine
answer
        muscarinic agonist, binds AChE but resists hydrolysis (making it longer acting); used for treatment of open-angle glaucoma; natural product; can also be used clinically for Sjorgen’s syndrome
question
            Cevimeline
answer
        synthetic pilocarpine-like molecule; approved for Sjorgen’s syndrome
question
            Oxotremorine
answer
        muscarinic selective; long acting (resists AChE hydrolysis); clinical use = experimental model of Parkinson’s disease tremor
