The suprarenal or adrenal glands, each perched over one of the kidneys, are
double glands. The core, or medulla, manufactures adrenalin, noradrenalin and a
small amount of dopamine. The outer layer of the gland is called the cortex. The
adrenal cortex produces three groups of corticosteroids; mineralocorticoids
(aldosterone) - control electrolyte and water balance, glucocorticoids
(cortisol)- influence carbohydrate
metabolism and sex steroid
hormones (androgens, DHEA).
