Briefly, what role if any, does each of the following hormones play when the body is subjected to stress: ACTH, ADH, aldosterone, cortisol, CRH, epinephrine and norepinephrine? Briefly, what role if any, does each of the following hormones play when the body is subjected to stress: ACTH, ADH, aldosterone, cortisol, CRH, epinephrine and norepinephrine?

Explanation / Answer

When the body is subjected to stress-

Adreno corticotropic hormone- it is secreted from anterior pituitary and acth stimulates the secretion of cortisol and little control over aldrosterone from the adrenal cortex

Adh- or vasopressin is stimulated by acth and it resorbs water from kidney and constrict the blood vessel causing increased blood pressure.

Aldosterone-Aldosterone is secreted by adrenal cortex and is a part of renin angiotensin system. It makes sodium to absorb and pottasium to excrete at kidney thus maintaining blood pressure during stress.

Cortisol- A part of adrenal cortex hormone. During stress it provides energy to body by increasing glucose levels by gluconeogenesis of proteins in liver thus it provides energy during stress

CRH- Is secreted by hypothalamus and it stimulates the secretion of ACTH from pituitary gland during stress. It also responsible for behaviour response during stress times.

Epinephrine and norepinephrine- Is secreted by adrenal cortex. It is a symphathetic hormone which increases blood glucose levels. Blood pressure, cardiac output, dilatation of Iris, and make the body to fight for stress.
