The fight-or-flight response is best described as a coordinated response involving which systems?

• A. Cognitive appraisal of threat
• B. Behavioral withdrawal response
• C. A coordinated autonomic and endocrine response involving the autonomic nervous system and HPA axis
• D. Long-term memory consolidation during stress

Answer: (C)

The fight-or-flight response is a coordinated autonomic and endocrine response, because it relies on rapid nervous system activation plus hormonal support to sustain the reaction. The autonomic nervous system, especially the sympathetic branch, kicks in right away to raise heart rate, increase respiration, dilate airways, and redirect blood to muscles. At the same time, the HPA axis is activated, releasing cortisol and other hormones that boost glucose availability and sustain energy for a longer duration. This combination allows the body to react quickly and remain prepared for action. It’s not about cognitive appraisal alone, nor only a behavioral withdrawal, and long-term memory processes come into play later rather than defining this immediate response.
