What is the hormone and structure involved in prolonged stress? Why is this damaging?

Solution

Upon stress the roles of two peptide hormones, corticotropin-releasing hormone (CRH) and arginine-vassopressin (AVP), have been widely studied. Stimulated by an environmental stressor, neurons in the hypothalamus secrete CRH and AVP.

CRH, is transported to the anterior pituitary, where it stimulates the secretion of corticotropin Consequently, corticotropin stimulates increased production of corticosteroids including cortisol, the primary actor directly impacting the stress response

Vasopressin, a small hormone molecule, increases reabsorption of water by the kidneys and induces vasoconstriction, the contraction of blood vessels, thereby raising blood pressure.

So continue stress can lead to high blood pressure that can further results in heart related disease. stress hormones get over-secreted, which affects the brain where memories are processed through and stored
