ADRENAL GLAND

an organ located above each kidney that produces various hormones. The medulla (inner part) of the adrenal gland secretes adrenaline (epinephrine). The cortex (outer part) secretes steroids such as cortisol and certain androgens. The adrenal cortex are stimulated to produce hormones by the pituitary hormone ACTH; reduced secretion (adrenal insufficiency) can lead to fatigue, anorexia and weight loss.
