Question

Quizplus · Accepted Answer

The neurotransmitter released by the axon of a sympathetic preganglionic neuron to communicate with the sympathetic postganglionic neuron is acetylcholine. This is because sympathetic preganglionic neurons are cholinergic, meaning they release acetylcholine at their synapses with postganglionic neurons. The postganglionic neurons of the sympathetic nervous system, on the other hand, release norepinephrine (noradrenaline) as their main neurotransmitter.
