| pseudostratified epithelium | An epithelium that gives a superficial appearance of being stratified because the cell nuclei are at different levels, but in which all cells reach the basement membrane, hence it is classed as a simple epithelium. (05 Mar 2000) |
|---|---|
| seminiferous epithelium | Specialised epithelium lining the seminiferous tubules containing developing and mature spermatozoa and sertoli cells. (12 Dec 1998) |
| simple epithelium | An epithelium having one layer of cells. (05 Mar 2000) |
| simple squamous epithelium | Epithelium composed of a single layer of flattened scalelike cells, such as mesothelium, endothelium, and that in the pulmonary alveoli. Synonym: pavement epithelium. (05 Mar 2000) |
| squamous epithelium | <pathology> An epithelium in which the cells are flattened. May be simple (e.g. Endothelium) or stratified (e.g. Epidermis). (18 Nov 1997) |
| stratified ciliated columnar epithelium | An epithelium consisting of several layers of cells with the deeper cells being polyhedral in form and the surface ones columnar with motile cilia, such as that which lines the foetal oesophagus. (05 Mar 2000) |
| stratified 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) |
| stratified squamous epithelium | An epithelium consisting of several layers of keratin containing cells in which the surface cells are flattened and scale-like and the deeper cells are polyhedral in form. Keratin filaments become progressively more abundant toward the surface, which on the dry surfaces of the body may consist of a layer of dead corneocytes. (05 Mar 2000) |
| sulcular epithelium | The stratified squamous epithelium lining the inner aspect of the soft tissue wall of the gingival sulcus. Synonym: sulcular epithelium. (05 Mar 2000) |
| surface epithelium | A layer of celomic epithelial cells covering the gonadal ridges as they are formed on the medial border of the mesonephroi near the root of the mesentery, the mesothelial covering of the definitive ovary. (05 Mar 2000) |
| inner dental epithelium | Inner enamel epithelium, the columnar epithelial layer of enamel matrix, secreting ameloblasts, of the odontogenic organ of a developing tooth. (05 Mar 2000) |
| intestinal epithelium | <pathology> The endodermally derived epithelium of the intestine varies considerably, but the absorptive epithelium of small intestine is usually implied. The apical surfaces of these cells have microvilli possibly to increase the absorptive surface, but probably also to provide a larger surface area for enzyme activity). The lateral sub apical regions have well developed junctional complexes. (10 Jan 1998) |
| olfactory epithelium | The epithelium lining the nose. (18 Nov 1997) |
| enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| transitional epithelium | A highly distensible pseudostratified epithelium with large polyploid superficial cells that are cuboidal in the relaxed state but broad and squamous in the distended state; occurs in the kidney, ureter, and bladder. (05 Mar 2000) |
