The mushroom poison muscarine can bind to receptors on ________.
A) cell bodies and dendrites of parasympathetic postganglionic neurons
B) cell bodies and dendrites of sympathetic postganglionic neurons
C) the hormone producing cells of the adrenal medulla
D) all effector cells stimulated by postganglionic cholinergic fibers

Question

Quizplus · Accepted Answer

Muscarine is a cholinergic agonist that can bind to all effector cells stimulated directly or indirectly by postganglionic cholinergic fibers, including those in the parasympathetic and sympathetic nervous systems. Muscarine cannot bind to hormone-producing cells of the adrenal medulla because those cells are part of the sympathetic nervous system and release catecholamines, not acetylcholine.
