Fight or Flight response
fight or flight response
The stress response is triggered by the amygdala, an area of the brain which associates sensory inputs with emotions like fear and anger. The amygdala sends a distress signal to the hypothalamus
The hypothalamus sends a message to the sympathetic nervous system, this triggers the release of adrenaline. Adrenaline causes increase in blood pressure and heart rate etc, fight or flight response. When the threat has passed, the parasymapathetic nervous system kicks in and relaxes you,
the fight or flight response is a sequence of activity with the body that is triggered in response to stress enabling us to react quickly to life-threatening situations.
