pseudostratified columnar epithelium

The paranasal air sinuses are lined with respiratory epithelium (ciliated pseudostratified columnar epithelium).

The respiratory epithelium lining the upper (cranial) airways is classified as ciliated pseudostratified columnar epithelium.

Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium.

As it rarely occurs as squamous or cuboidal epithelia, it is usually considered synonymous with the term pseudostratified columnar epithelium.

The mucous membrane also undergoes a transition from ciliated pseudostratified columnar epithelium to simple cuboidal epithelium to simple squamous epithelium.

The olfactory segment is lined with a specialized type of pseudostratified columnar epithelium, known as olfactory epithelium, which contains receptors for the sense of the smell.

It has nipple-like structures with fibrovascular cores (papillae) that are long in relation to their width (villus-like), which are covered with a glandular pseudostratified columnar epithelium.

The majority of cells composing the ciliated pseudostratified columnar epithelium are of three types: a) ciliated cells, b) goblet cells, and c) basal cells.
