Adrenal gland(s)

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).
