C) muscarinic
D) nicotinic

Question

Quizplus · Accepted Answer

Preganglionic neurons release the neurotransmitter acetylcholine, which binds to nicotinic receptors on postganglionic neurons. This results in activation of the postganglionic neuron and transmission of the signal to the target organ or tissue. Therefore, increased activity in preganglionic neurons would most directly and strongly activate nicotinic receptors.
