- Bodily Response to Stress
- Sympathomedullary Pathway
- Stressor stimulates sympathetic branch of nervous system
- Adrenal medulla releases adrenaline into bloodstream
- Adrenaline causes 'fight or flight' response
- Increase in heart rate, decrease in digestion, dilated pupils
- Adrenaline causes 'fight or flight' response
- Adrenal medulla releases adrenaline into bloodstream
- Response to acute stress (sudden)
- Uses nerves
- Stressor stimulates sympathetic branch of nervous system
- Pituitary-adrenal System
- Response to chronic stress (on-going)
- Uses hormones
- Hypothalamus stimulates pituitary gland
- Pituitary gland releases ACTH
- ACTH travels in bloodstream to adrenal glands which release cortisol
- Cortisol stimulates release of blood sugar to cope with stressor but reduces cognitive function and immune system
- ACTH travels in bloodstream to adrenal glands which release cortisol
- Pituitary gland releases ACTH
- Sympathomedullary Pathway
