Receptors On The Autonomic Effector Cells

The receptors for acetylcholine and related drugs (cholinoreceptors) and for norepinephrine and related drugs (adrenoceptors) are different. Acetylcholine will not interact with receptors for norepinephrine, and nor-epinephrine will not interact with cholinoreceptors. These receptors are selective not only for their respective agonists but also for their respective antagonist drugs; that is, drugs that antagonize or block acetylcholine at cholinoreceptors will not antagonize norepi-nephrine at adrenoceptors and vice versa.
