Question

what controls the fight-or-flight response?
○ endocrine glands
○ sympathetic nervous system
○ cerebral cortex
○ activated brain synapses

Explanation:

The fight-or-flight response is an involuntary physiological reaction to stress or danger. The sympathetic nervous system, a division of the autonomic nervous system, directly triggers this response by activating bodily changes like increased heart rate, dilated pupils, and redirected blood flow to muscles. Endocrine glands (like the adrenal glands) support it by releasing hormones, but they act in response to signals from the sympathetic nervous system. The cerebral cortex handles conscious processing, and activated synapses are a general cellular mechanism, not the specific controller of this response.

Answer:

sympathetic nervous system
