The adrenal gland sits directly on top of the kidneys and consists of 2 separate organs, the cortex and the medulla . The medulla (inner portion) produces and secretes the catecholamine hormones , epinephrine (adrenaline) and norepinephrine (noradrenaline). The cortex (outer portion) produces the corticosteroids , glucocorticoids (such as cortisol) and mineralocorticoids (aldosterone).
