Question

Which of the following is most characteristic of the parasympathetic nervous system?
A) Adrenergic
B) Norepinephrine
C) Fight-or-flight response

Accepted Answer

The parasympathetic nervous system is responsible for the "rest-and-digest" or "feed-and-breed" response, which includes digestion and sexual arousal. The other choices refer to characteristics of the sympathetic nervous system, which is responsible for the "fight-or-flight" response and uses norepinephrine and adrenergic receptors.
