Question

which specific subdivision of the nervous system dominates in stressful or emergency situations and prepares the body for strenuous physical activity? (1 point) ○ sympathetic nervous system ○ parasympathetic nervous system ○ somatic nervous system ○ autonomic nervous system

Explanation:

The sympathetic nervous system is responsible for the "fight - or - flight" response. In stressful or emergency situations, it increases heart rate, dilates pupils, and redirects blood flow to muscles, preparing the body for strenuous physical activity. The parasympathetic nervous system is for "rest - and - digest". The somatic nervous system controls voluntary movements. The autonomic nervous system is a broader category that includes both sympathetic and parasympathetic.

Answer:

sympathetic nervous system
