The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: zona glomerulosa, the zona fasciculata and the zona reticularis.

English to English translation of 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.
