Question

Quizplus · Accepted Answer

Nicotine activates nicotinic receptors, which are a type of cholinergic receptor found on neurons that use acetylcholine as their neurotransmitter. Muscarinic receptors also bind acetylcholine, but they are not activated by nicotine. Adrenergic receptors bind adrenaline and noradrenaline, not nicotine. Multipolar neurons have multiple dendrites and one axon, but this is not relevant to nicotine's effects on the nervous system.
