What's the difference between cortical and epidermis?

Cortical


Definition:

  • (a.) Belonging to, or consisting of, bark or rind; resembling bark or rind; external; outer; superficial; as, the cortical substance of the kidney.

Example Sentences:

  • (13) Since only a few of these medium sized terminals in any one cluster degenerate after tectal lesions, and none degenerate after cortical lesions, it is suggested that the morphological arrangement of these clusters may permit the convergence of axons from several sources, some of which are unidentified, onto the same dendritic segment.

  • (18) The effects of angiotensin II (ANG II) or angiotensin III (ANG III) on renal cortical blood flow (CBF) or papillary blood flow (PBF) were investigated in Inactin-anesthetized young rats with the use of laser-Doppler flowmetry.
  • (19) Results are interpreted in terms of a hypothesized selective effect of alcohol on frontal cortical inhibitory functions.
  • (20) Axosomatic and axodendritic contacts were present in the cortices of the fetuses.

Epidermis


Definition:

  • (v. t.) The outer, nonsensitive layer of the skin; cuticle; scarfskin. See Dermis.
  • (v. t.) The outermost layer of the cells, which covers both surfaces of leaves, and also the surface of stems, when they are first formed. As stems grow old this layer is lost, and never replaced.

Example Sentences:

  • (1) The observed staining indicated that the epithelium of the external auditory meatus has a pattern of keratin expression typical of epidermis in general and the epithelium of the middle ear resembles simple columnar epithelia.
  • (2) A comparison between TPA and cytokeratins was also made by immunoblotting which revealed immunoreactivity of antibodies to TPA with cytokeratin polypeptides of different species (man, mouse) and organs (epidermis, liver), particularly with the cytokeratin component 8 of human liver and the related component A of mouse liver.
  • (3) The enzyme profile of the epidermis was investigated in relation to depth.
  • (4) It increased linearly in both the epidermis and dermis, reaching nearly 100% 24 hr following its injection on Day 8.
  • (5) UVB irradiation augmented the beta-adrenergic adenylate cyclase response of pig skin epidermis in vitro.
  • (6) The kinetics of both the solube and particulate enzymes from epidermis of some elderly patients with either diabetes or ischaemia showed some differences from the kinetics of enzymes from healthy epidermis from younger individuals.
  • (7) These results indicate that uninvolved psoriatic epidermis has an increased capacity to metabolize free AA into 12-lipoxygenase products.
  • (8) Besides the rough, wrinkled, and brown or black surface of the fingertips, microwrinkles of the epidermis occur on the skin ridges, which have so far not been described.

  • (10) The synthesis of uPA as a precursor with reduced enzymatic activity as well as decreased affinity for inhibitors is likely to be a mechanism by which normal epidermis regulates plasminogen activation in vivo.
  • (11) The bone marrow derivation of dThy-1+EC is now well established: dThy-1+EC carry Ly-5 determinants whose expression is restricted to cells of the hemopoietic differentiation pathway, and studies using Thy-1-disparate radiation bone marrow chimeras have revealed the presence of donor-type Thy-1+ cells within the epidermis; by immunoelectron microscopy, these cells represent dThy-1+EC.
