HPA axis controls levels of cortisol - activated by physical or emotional stressors. 3. When chronic stressor is perceived the hypothalamus activates. 4. A region of the hympothalamus, paraventricular nucleus (PVN), causes corticoptrophin releasing factor (CRF) to be released. 5. CRF travels to the pituitary gland. Pituitary gland releases adrenocorticotrophin hormone (ACTH). 6. ACTH travels to the adrenal gland above the kidneys. 7. Part of the adrenal gland, the adrenal cortex, causes cortisol to be released. Cortisol has postive effects: + lower pain sensitivity + quick burst of energy and negative effects: - impaired cognitive performance - higher blood pressure - lowered immune response |
