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.vis·u·al cor·texthe region of the cerebral cortex occupying the entire surface of the occipital lobe, and composed of Brodmann areas 17-19. Brodmann area 17 (which is also called striate cortex or area because the line of Gennari is grossly visible on its surface) is the primary visual cortex, receiving the visual radiation from the lateral geniculate body of the thalamus. The surrounding Brodmann areas 18 (parastriate cortex or area) and 19 (peristriate cortex or area) are probably involved in subsequent steps of visual information processing; Brodmann area 18 is referred to as the secondary visual cortex. Synonym(s): visual areavis·u·al cor·tex (vizh'ū-ăl kōr'teks) The region of the cerebral cortex occupying the entire surface of the occipital lobe, and composed of Brodmann areas 17-19. Area 17 (which is also called the striate cortex or area because the line of Gennari is grossly visible on its surface) is the primary visual cortex, receiving the visual radiation from the lateral geniculate body of the thalamus.
