pseu·do·strat·i·fied ep·i·the·li·um

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.

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.

pseudostratified epithelium

Epithelium in which the bases of cells rest on the basement membrane but the distal ends of some do not reach the surface. Their nuclei lie at different levels, giving the appearance of stratification.

Salivary duct cysts occur typically in close association with salivary gland tissue and possess partial or complete epithelial lining (thus distinguishing them from mucous extravasation cysts) ranging from 1 or 2 layers of flat to cuboidal epithelial cells, occasionally containing oncocyte-like cells, to thicker pseudostratified columnar epithelium or stratified squamous epithelium.
The epithelium of crop appears to be pseudostratified columnar epithelium that is composed of only one-cell type (i.
Given their similar location and their large numbers of basally-directed secretion granules, the cells of the primordial spine's ectoderm-derived pseudostratified columnar epithelial layer may be identified as ameloblasts.
The upper half of the sinus tract was covered with keratinizing squamous epithelium, and the lower half with nonciliated pseudostratified columnar epithelium.
6) Histologically, branchial sinuses are lined by pseudostratified columnar epithelium with lymphoid tissue; in rare cases, salivary tissue or sebaceous glands are also present.
The sinus tract is typically lined with benign squamous or pseudostratified columnar epithelium.

4,7) This theory is supported by the fact that the nasolacrimal ducts are lined with pseudostratified columnar epithelium, which is the type of epithelium found in the nasolabial cyst cavity.
Because the uncinate process shares a similar pseudostratified columnar epithelial lining with the surrounding nasal cavity, polypoid changes can alter the appearance of structures in the middle meatus.
