Biology of Stress Sympathetic Adrenal- Medullary System (SAM) Hypothalamic-Pituitary- Adrenal Axis (HPA) O Initiates the release of adrenaline and norepinephrine into the bloodstream from the adrenal glands O Produces the fight- flight response to stress O Hypothalamus communicates with the pituitary gland, which tells the adrenal glands to release cortisol (hormone) O Cortisol boosts the energy available for dealing with a stressor Occur at the same time; HPA can continue much longer than the SAM response
