Fight or Flight response

• 1. During fight or flight, the hypothalamus recognises a stressor and activates the pituitary gland which triggers the sympathetic division of the autonomic nervous system.
• 2. Adrenaline (a hormone) is then released from the adrenal medulla.
• 3. the release of adrenaline causes an increase in heart rate, increase in blood pressure, inhibition of digestion, dilated pupils, mouth dryness and sweating
• 4. after the threat has passes, the parasympathetic division is activated and thus your heart rate decreases, breathing rate decreases, pupils constrict and digestion is stimulated again.
• The negative effects of fight or flight is that if you encounter a stressor or stressful event in real life like an exams, then your flight or fight response might kick in leading to a decrease in normal life performance.
