Answer #1

The adrenal medulla releases the hormones epinephrine and norepinephrine. These are released when there is sympathetic stimulation to the adrenal medulla gland.

The function of these hormones is mainly on the cardiovascular system which include increase in the blood pressure and increase in cardiac output. This occurs by action on the heart which increases force of contraction and on blood vessels which causes vasoconstriction.

On kidney, it causes increase in the glomerular filtration rate. On metabolism, it increases the blood sugar levels.

Hope this helps... Thank you!!!

The hypothalamic-pituitary-adrenal axis includes corticotropin releasing hormone (CRH) from the hypothalamus, adrenocorticotropic hormone (ACTH) from the pituitary, and cortisol from the adrenal gland. In this system, CRH stimulates the release of ACTH, which stimulates the release of cortisol that exerts a negative feedback effect on both CRH and ACTH. Until only recently, there was no good tool to measure serum ACTH. Therefore, to evaluate whether pathologically high cortisol was related to ACTH, the “Dexamethasone suppression test” was invented. The elements...
