What's the difference between endoskeleton and epidermis?

Endoskeleton


Definition:

  • (n.) The bony, cartilaginous, or other internal framework of an animal, as distinguished from the exoskeleton.

Example Sentences:

  • (1) The separate developmental origin of the exo- and endoskeletons.
  • (2) Fractionation of pluteus stage embryos demonstrates that the protein is localized primarily with cells that form the syncytium of primary mesenchyme that elaborates the larval endoskeleton; furthermore, immunofluorescence localizes the epitope to the periphery of the endoskeleton in situ.
  • (3) At present the detailed mechanism for transmembrane interactions is not known and a protein linked to the endoskeleton as well as to the exoskeleton has not been described as yet.
  • (4) Sensitivity was dependent on body composition (i.e., exo- vs. endoskeleton), trophic level, and life stage.
  • (5) The heavy chain is known to bind strongly to the endoskeleton protein actin.
  • (6) Prolyl hydroxylation of cartilaginous endoskeleton showed an approximately 25% decrease at 20 degrees C.
  • (7) The durability and function of three ankle-foot prostheses fabricated using a naturally articulated, fresh cadaveric human bone endoskeleton set in a fiber reinforced rubber shell were studied.
  • (8) The implants were dome shaped and did not have a metal endoskeleton.
  • (9) The endoskeleton foot compared favorably with the Jaipur ankle-foot prosthesis.
  • (10) It is suggested that the sarcoplasmic reticulum may be a part of the "endoskeleton" of the cell and may play a role in maintaining the shape and location of the nucleus.
  • (11) Calcified cartilage as a tissue type in the endoskeleton of sharks is a primitive vertebrate characteristic.
  • (12) This report describes the construction and evaluation of an ankle-foot prosthesis using human cadaveric bones as the endoskeleton inside a fiber-reinforced vulcanized rubber shell.

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.
  • (9) At an ultrastructural level, 15-1 immunogold-labeling in the epidermis was confined to the surface of cells exhibiting Birbeck granules.
  • (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.
  • (12) Exposure of neutrophils to AS resulted in deactivation to AS but not to Escherichial coli or Staphylococcus epidermis culture filtrate.
  • (13) The delta-PKC-like kinase of mouse epidermis (p82-kinase) was down-regulated after topical application of 12-O-tetradecanoylphorbol-13-acetate (TPA) to mouse skin.
  • (14) The purpose of this report is to present the kinetics of reduction of epidermal mass following the production of the epidermal hyperplasia as the epidermis returns to its normal thickness during the period of regression.
  • (15) Immunoreactivity was restricted to the periderm and intermediate layers of fetal epidermis at 55 d of gestation, when the first wave of wool follicles are initiated.
  • (16) In hatched larvae around developmental stage 46, strong expression of 2NI-36 was observed in several tissues including the vascular endothelium, the pigmented epithelium and the inner layer of skin epidermis.
  • (17) Our results show that two major types of terminally differentiating keratinocytes can be distinguished in human epidermis, i.e.
  • (18) This results suggest the presence of structural abnormalities in epidermis of EB simplex.
  • (19) By contrast, epidermal Langerhans cell (LC) HLA-DR and T6 expressions in normal epidermis were greatly reduced by an identical dose of UVB.
  • (20) This calcium-binding protein was not in skin epidermis, but was confined to the dermal layer.
