Question

Most autonomic neurons release acetylcholine as the neurotransmitter. Name the type of neuron that releases norepinephrine instead of ACh.

Answer 1

Parasympathetic neurons release norepinephrine instead of ACh. The postganglionic fibers of the sympathetic and parasympathetic divisions both release neurotransmitters that bind to receptors on their targets.

Step-by-step explanation:

Parasympathetic neurons release norepinephrine instead of ACh. The postganglionic fibers of the sympathetic and parasympathetic divisions both release neurotransmitters that bind to receptors on their targets. Postganglionic sympathetic fibers release norepinephrine, whereas postganglionic parasympathetic fibers release ACh. The difference in neurotransmitter release determines which division of the autonomic nervous system is exerting control on the target organ.
