General Adaptation Syndrome High The body's resistance to stress can onl last so long before exhaustion sets in Stress resistance Stressor occurs Low Phase1 Ph ase 2 Phase 3 Alarm reaction Resistance Exhaustion (mobilize (cope with stressor) (reserves resources depleted)
General Adaptation Syndrome
Mechanism of stress (1) LC/NE ( locus ceruleus-norepinephrine /sympathetic-adrenal meddula axis)---- Cannon ( 2) HPA( Hypothalamus-pituitary-adrenal cortex system)----- Selye (3)Other hormones (4) AP( Acute phase protein (5) HSP( Heat shock protein, stress protein Flight or Fight response
