stratified ciliated epithelium

anatomy

Quick Summary

Stratified ciliated epithelium is a type of tissue composed of multiple layers of cells, with the surface cells being ciliated (possessing hairlike projections) and columnar in shape. This specialized epithelium lines certain parts of the respiratory passages, such as the trachea and bronchi, as well as the vas deferens and epididymis in males.1

Epithelium, in general, forms continuous sheets of cells that cover surfaces and can be protective, absorptive, or secretory. Stratified epithelium, in particular, is found in areas exposed to friction, like the skin and mucous membranes of the mouth and esophagus. The ciliated nature of stratified ciliated epithelium aids in moving substances, such as mucus and trapped particles, along these tracts.12
