Then, the CRH signals the pituitary gland to release ACTH, which signals for a final outcome of cortisol being released. This continuous feedback system between CRH, ACTH, and cortisol is what makes up the hypothalamic-pituitary-adrenal axis (HPA axis). When there is continuous stress placed upon the body, the HPA axis has a more difficult time keeping the feedback system in balance for reasons that could include the circadian rhythm being thrown off and the heightened levels of cortisol releases depending on how high the levels of stress reach. Cortisol works in an inhibitory feedback loop—it blocks the secretion of corticotropin-releasing hormones and prevents the interactions involving glucocorticoid secretion. When under constant stress, the feedback inhibition becomes disrupted, and increased levels of cortisol become released from the adrenal cortex when they should not be. Thus, a stressed student experiencing negative stress would have increased glucocorticoid
