adrenal cortex  the outer, firm layer comprising the larger part of the adrenal gland; it secretes many steroid hormones including mineralocorticoids, glucocorticoids, androgens, 17-ketosteroids, and progestins.

cerebellar cortex , cortex cerebella´ris the superficial gray matter of the cerebellum.

cerebral cortex , cortex cerebra´lis the convoluted layer of gray substance covering each cerebral hemisphere; see archicortex, paleocortex, and neocortex.

cortex len´tis  the softer, external part of the lens of the eye.

motor cortex  see under area.

provisional cortex  the cortex of the fetal adrenal gland that undergoes involution in early fetal life.

renal cortex , cortex re´nis the outer part of the substance of the kidney, composed mainly of glomeruli and convoluted tubules.

striate cortex  the part of the occipital lobe of the cerebral cortex that is the primary receptive area for vision.

cortex of thymus  the outer part of each lobule of the thymus; it consists chiefly of closely packed lymphocytes (thymocytes) and surrounds the medulla.

visual cortex  the area of the occipital lobe of the cerebral cortex concerned with vision.

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 gray matter of the cerebellum.

cerebral cortex (cortex cerebra´lis) the convoluted layer of gray matter covering each 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 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.
