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.

re·nal cor·tex

[TA]
the part of the kidney consisting of renal lobules in the outer zone beneath the capsule and the lobules of the renal columns that are extensions inward between the pyramids; contains the renal corpuscles, medullary rays, and proximal and distal convoluted tubules.
Synonym(s): cortex renalis [TA]

renal cortex

the highly vascularized granular outer layer of the kidney, containing approximately 1.25 million glomeruli and convoluted tubules, which filter body wastes from the blood, reclaim useful materials, and dispose of the remainder as urine.

re·nal cor·tex

(rē'năl kōr'teks) [TA]
The part of the kidney consisting of renal lobules in the outer zone beneath the capsule and the lobules of the renal columns that are extensions inward between the pyramids; contains the renal corpuscles and the proximal and distal convoluted tubules.

cortex

pl. cortices [L.] an outer layer, as the bark of the trunk or root of a tree, or the outer layer of an organ or other structure, as distinguished from its inner substance.

adrenal cortex
the outer, firm layer comprising the larger part of the adrenal gland; it secretes a number of hormones. See corticosteroid, aldosterone, mineralocorticoid, glucocorticoid.
cerebellar cortex
the superficial gray matter of the cerebellum.
cerebral cortex, cortex cerebri
the convoluted layer of gray matter covering each cerebral hemisphere. See also cerebral cortex.
renal cortex
the smooth-textured outer layer of the kidney, composed mainly of renal corpuscles and convoluted tubules, extending in columns between the pyramids.

Zhu and colleagues found that the MRI revealed cystic components, poorly defined tumour, isointense tumour on T1-weighted imaging and iso- or hypointense on T2-weighted imaging; the MRI also demonstrated lower enhancement within the tumour than the renal cortex and medulla.
