Adrenal glands

Also found in: Dictionary, Thesaurus, Encyclopedia.

adrenal glands

The small internally secreting (ENDOCRINE) organs which sit like triangular caps one on top of each KIDNEY (hence the name). Each adrenal has two distinct parts, the inner core, which produces ADRENALINE, and an outer layer (the cortex) which produces various steroid hormones. Formerly known as suprarenal glands, which, of course, means the same thing.

Adrenal glands

The two glands that are located on top of the kidneys. These glands secrete several hormones, including the glucocorticoids which, among other things, influence the way the immune system works, and the mineralocorticoids, which affect retention of water and sodium.
