Which epithelium type includes cilia and is described as pseudostratified columnar cilia epithelium?

• A. Pseudostratified columnar epithelium
• B. Pseudostratified columnar cilia epithelium
• C. Simple columnar epithelium
• D. Stratified cuboidal epithelium

Answer: (B)

The main idea here is recognizing a tissue type that specifically includes cilia on its apical surface. When a description mentions cilia, it points to a pseudostratified columnar epithelium that is ciliated, which is characteristic of the respiratory tract where the cilia help move mucus and trapped particles out of the airways. This distinguishes it from plain pseudostratified columnar epithelium (which may not have cilia), simple columnar epithelium (a single layer that is not described as ciliated in this context), and stratified cuboidal epithelium (a different multilayered, non-ciliated type). The presence of cilia is the defining feature that links the tissue to functions like mucociliary clearance, lining areas such as the trachea and bronchi. Therefore, the option that explicitly includes cilia in its name best matches the description.
