adrenal cortex[ə′drēn·əl ′kȯr·teks] (anatomy) The cortical moietie of the suprarenal glands which secretes glucocorticoids, mineralocorticoids, androgens, estrogens, and progestagens. adrenal cortex
cortex [kor´teks] (pl. cor´tices) (L.) the outer layer of an organ or other structure, as distinguished from its inner substance or medulla. adj., adj cor´tical.adrenal cortex (cortex of adrenal gland) the outer, firm layer comprising the larger part of the adrenal gland; it secretes mineralocorticoids, androgens, and glucocorticoids.cerebellar cortex the superficial matter" >gray matter of the cerebellum.cerebral cortex (cortex cerebra´lis) the convoluted layer of matter" >gray matter covering each hemisphere" >cerebral hemisphere. See also brain.renal cortex the granular outer layer of the kidney, composed mainly of glomeruli and convoluted tubules, extending in columns between the pyramids that constitute the renal medulla.striate cortex part of the occipital lobe that receives the fibers of the radiation" >optic radiation and serves as the primary receiving area for vision. Called also first visual area.visual cortex the area of the occipital lobe of the cerebral cortex concerned with vision; the striate cortex is also called the first visual area, and the adjacent second and third visual areas serve as its association areas.cortex of suprarenal gland [TA] the outer part of the adrenal gland, consisting of three zones from without inward: zona glomerulosa, zona fasciculata, and zona reticularis; this part of the adrenal cortex yields steroid hormones such as corticosterone, deoxycorticosterone, and estrone.

The outer portion of the adrenal glands that produces several steroid hormones, including cortisol and aldosterone.Adrenal Cortex The firm, outer yellow layer of the adrenal gland which is derived from embryonic mesoderm and consists of 3 layers:
• Zona glomerulosa, the outermost layer, which secretes mineralocorticoids, primarily aldosterone
• Zona fasciculata, the middle layer, which secretes glucocorticoids, primarily cortisol, both at baseline levels and in bursts, when so commanded by ACTH from the anterior pituitary gland
• Zona reticularis, the innermost layer, which secretes androgens, primarily dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEA-S).adrenal cortex The outer zone of the ADRENAL GLAND that secretes CORTISOL, sex hormones (ANDROGENS) and ALDOSTERONE. See also ADRENAL MEDULLA.Adrenal cortexThe outer tissue of the adrenal gland. It produces a group of chemically related hormones called corticosteroids that control mineral and water balance in the body and include aldosterone and cortisol.Mentioned in: Adrenal Gland Scancor·tex of su·pra·re·nal gland (kōrteks sūpră-rēnăl gland) [TA] The outer part of the suprarenal gland.
