Any one of hormones elaborated by the adrenal cortex (excluding the sex hormones of adrenal origin) that influence or control key processes of the body. These processes include carbohydrate and protein metabolism, maintenance of serum glucose levels, electrolyte and water balance, and functions of the cardiovascular system, the skeletal muscle, the kidneys, and other organs. The corticosteroids synthesized by the adrenal glands include the glucocorticoids and the mineralocorticoids. The principal glucocorticoids are cortisol and corticosterone. The only physiologically important mineralocorticoid in humans is aldosterone.
