• In lampreys, the cornea is solely an extension of the sclera, and is separate from the skin above it, but in more advanced vertebrates it is always fused with the skin to form a single structure, albeit one composed of multiple layers. (wikipedia.org)
  • The junction between cornea and sclera is called the limbus. (medcell.org)
  • An annular transitional zone, approximately 1 mm wide, between the cornea and the bulbar conjunctiva and sclera. (bvsalud.org)

  • The human cornea has six layers Corneas of other primates have five known layers. (wikipedia.org)
  • dua's layer : the fourth layer of cornea is dua's layer which is nothing but a thickened stroma in the poster most part of the stroma this was recently declared as the newly added structure, thus making the cornea a 6 layered structure rather than just 5 layer structure. (wikipedia.org)
  • The corneo-scleral layer supports the structure of the eye with its tough fibroelastic composition. (medcell.org)

  • Because transparency is of prime importance, the healthy cornea does not have or need blood vessels within it. (wikipedia.org)
  • Medical terms related to the cornea often start with the prefix "kerat-" from the Greek word κέρας, horn. (wikipedia.org)
