epithelium

 [ep″ĭ-the´le-um] (pl. epithe´lia) (Gr.)
the cellular covering of internal and external surfaces of the body, including the lining of vessels and other small cavities. It consists of cells joined by small amounts of cementing substances. Epithelium is classified into types on the basis of the number of layers deep and the shape of the superficial cells.
ciliated epithelium epithelium bearing vibratile, hairlike processes (cilia) on its free surface.
columnar epithelium epithelium whose cells are of much greater height than width.
cuboidal epithelium epithelium whose cells are of approximately the same height and width, and appear square in transverse section.
germinal epithelium thickened peritoneal epithelium covering the gonad from earliest development; formerly thought to give rise to germ cells.
glandular epithelium that composed of secreting cells.
pigmentary epithelium (pigmented epithelium) that made of cells containing granules of pigment.
sense epithelium (sensory epithelium) neuroepithelium (def. 1).
simple epithelium that composed of a single layer of cells.
squamous epithelium that composed of flattened platelike cells.
stratified epithelium epithelium made up of cells arranged in layers.
transitional epithelium a type characteristically found lining hollow organs, such as the urinary bladder, that are subject to great mechanical change due to contraction and distention; originally thought to represent a transition between stratified squamous and columnar epithelium.

simple epithelium with cells appearing as squares in a vertical section but as polyhedra in surface view.

cuboidal epithelium

n.
Epithelial tissue consisting of one or more cell layers, the most superficial of which is composed of cube-shaped prismatic cells.

The induced tumour were composed of cuboidal epithelium with microvillous border originating from lining epithelium of the duct; presence of spindle shaped cells were identified as of myoepithelial origin.
The results obtained demonstrate that after prenatal exposure to phenytoin, despite the absence of significant alterations in nuclear shape, there were changes in nuclear size in the cuboidal epithelium of lateral ventricles in rat fetuses, reflected mainly through reduction in longest axis followed by reduction in other nuclear size parameters.
In one large series of 64 cysts, 41% of cysts showed pseudostratified columnar epithelium only, and in, respectively, 14% or 23% stratified squamous epithelium or cuboidal epithelium was also present.
Although their cause has not been clearly determined, they are known to be retention cysts that are lined with columnar or cuboidal epithelium.
Histopathological examination showed atrophic and dilated follicles lined by low cuboidal epithelium surrounded by abundant acellular homogenous pink substance along with fat infiltration, which stained positive with congo red and exhibited apple green birefringence under polarized light.
Microscopically, multilocular cystic nephroma demonstrates multilocular cysts lined by a single layer of flattened, low, cuboidal epithelium with eosinophilic cytoplasm and no nuclear atypia.
8%) (figure 2), and simple cuboidal epithelium in two (11.
Microscopic examination revealed that the cyst wall was lined with low cuboidal epithelium at places and pseudostratified columnar epithelium at other places.
Surrounding the main pancreatic duct along its length and under the cuboidal epithelium was abundant ovarian-type stroma with focal clusters of luteinized cells (Figure 3).
We found that (1) in most cases, the types of epithelium were generally the same in both areas--pseudostratified cylindrical ciliated epithelium with goblet cells (respiratory epithelium), stratified cuboidal epithelium, and stratified squamous nonkeratinized epithelium; (2) the APINC had more respiratory epithelium than the APS; (3) the APS had more squamous epithelium than the APINC; (4) the basement membrane of the APINC was thicker than that of the APS; (5) moderate chronic inflammatory infiltrate was more common in the APINc, and mild infiltrate was more common in the APS; and (6) the APINC had more mucous glands and the APS had more serous glands.
3,22) Microscopically, it consists of relatively uniform ductules lined by bland cuboidal epithelium and separated by fibrotic stroma, sometimes containing dense chronic inflammation.
