Quizplus · Accepted Answer

The neurotransmitter released at the autonomic ganglion by the preganglionic neuron is acetylcholine. This is a cholinergic synapse, where acetylcholine is the neurotransmitter used in the pre-to-post synapse. Norepinephrine or epinephrine would be used in a post-ganglionic adrenergic synapse. Dopamine and serotonin are not commonly used in the autonomic nervous system.
