Question

a major function of the ______ division of the nervous system is the fight-or-flight response in reaction to a threat.

multiple choice

○ somatic

○ sympathetic

○ central

○ parasympathetic

Explanation:

The sympathetic division of the autonomic nervous system triggers the "fight - or - flight" response to threats. The somatic system controls voluntary movements, the central nervous system (brain/spinal cord) is not a division for this response, and the parasympathetic is for "rest - and - digest", so sympathetic is correct.

Answer:

B. sympathetic
