| keratinising epithelium | <cell biology> An epithelium such as vertebrate epidermis in which a keratin rich layer is formed from intracellular cytokeratins as the outermost cells die. (18 Nov 1997) |
|---|---|
| laminated epithelium | <pathology> An epithelium composed of multiple layers of cells, only the basal layer being in contact with the basal lamina. The basal layer is of stem cells that divide to produce the cells of the upper layers, in skin, these become heavily keratinised before dying and being shed as squames. Stratified epithelia usually have a mechanical or protective role. (18 Nov 1997) |
| lining epithelium | An epithelium lining a duct, cavity or vessel, that is not particularly specialised for secretion or as a mechanical barrier. Not a precise classification. (18 Nov 1997) |
