ANATOMY

Detailed explanation-1: -The pseudostratified columnar epithelium helps in the secretion of mucus, protection of the respiratory tract and the inner ear from the foreign particles, absorption of the excess fluid, and the transport of the substances (such as enzymes, hormones, sperms).

Detailed explanation-2: -The epididymis has a smooth, even epithelium lining its lumen; while the efferent ducts are more scalloped in appearance. Both are examples of pseudostratified columnar epithelium. Especially note the stereocilia (long microvilli) of the epididymis.

Detailed explanation-3: -Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. In pseudostratified epithelium, nuclei of neighboring cells appear at different levels rather than clustered in the basal end.

Detailed explanation-4: -Types of epithelial cells in your body Simple columnar epithelium: This type of epithelium is often specialized for absorption and usually has apical cilia or microvilli. These cells line your stomach and intestines.

Detailed explanation-5: -The cilia lining the pseudostratified columnar epithelium beat in coordinated waves to carry mucus, trapped particles, and cells from the lower respiratory tract to the nasopharynx.
