Fight or flight responses are mediated by
Fight or flight responses are mediated by
Updated On: Feb 24, 2026
- Parasympathetic division of Autonomous nervous system
- Sympathetic division of Automonous nervoussystem
- Serotonergic nervous system
- Histaminergic nervous sytem
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The sympathetic nervous system mediates the fight or flight response by preparing the body for stress (increasing heart rate, redirecting blood flow, etc.). It is responsible for the body’s reaction to threats.
Parasympathetic system: Rest and digest (opposite of fight or flight).
Serotonergic & Histaminergic systems: Not directly related to fight or flight.
