What type of epithelium lines the conchae, meatuses and paranasal sinuses?

APseudostratified ciliated columnar epithelium
BStratified squamous keratinised epithelium
CSimple squamous non-ciliated epithelium
DSimple cuboidal secretory epithelium
Answer & Solution
Correct answer: A. Pseudostratified ciliated columnar epithelium
1. Respiratory epithelium is the specialised lining of most of the conducting zone. 2. It is pseudostratified ciliated columnar epithelium containing goblet cells. 3. The cilia sweep mucus and trapped debris toward the throat, which only a ciliated lining can do. 4. Simple squamous epithelium appears at the alveoli instead, and stratified squamous epithelium appears lower down in the oropharynx. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 22 "The Respiratory System", section 22.1 Organs and Structures of the Respiratory System_
