Question

Quizplus · Accepted Answer

Nicotinic receptors respond to acetylcholine released from both sympathetic and parasympathetic preganglionic fibers. They are found in autonomic ganglia and the adrenal medulla, as well as in the neuromuscular junction of skeletal muscle. They do not bind with norepinephrine nor are they primarily found in the heart.
