Question

current attempt in progress
your friend jumps out at you from behind a wall and scares you. your heartbeat increases suddenly, and your stomach feels strange. this represents stimulation of the ______ nervous system.
o parasympathetic
o central
o sympathetic
o somatic

Explanation:

The sympathetic nervous system is responsible for the "fight - or - flight" response. When scared (as in the given situation), it activates, causing an increased heartbeat and other physiological changes. The parasympathetic nervous system is for "rest - and - digest" (opposite of the described response). The central nervous system consists of the brain and spinal cord (not directly this specific response). The somatic nervous system controls voluntary movements (not relevant here).

Answer:

sympathetic
