Question

multiple cholce question
what neurotransmitters do the neurons of the autonomic nervous system secrete?
o acetycholine only
o acetycholine and norepinephrine
o norepinephrine only

Explanation:

The autonomic nervous system has two main divisions: the sympathetic and parasympathetic. Neurons in the autonomic nervous system secrete neurotransmitters. Preganglionic neurons (in both sympathetic and parasympathetic divisions) secrete acetylcholine. Postganglionic neurons: in the parasympathetic division secrete acetylcholine, and in the sympathetic division (most) secrete norepinephrine. So overall, the neurons of the autonomic nervous system secrete both acetylcholine and norepinephrine.

Answer:

Acetycholine and norepinephrine
