Question

The type of tissue lines the nasal passage, bronchioles, and fallopian tubes is:

• A. Columnar ciliated epithelium
• B. Cuboidal epithelium
• C. Neurosensory epithelium
• D. Germinal epithelium
• E. Stratified columnar epithelium

Answer 1

The correct option is A Columnar ciliated epithelium

• Ciliated epithelium is made simple columnar cells but possesses fine hair-like cilia on their free surfaces. These cells are found in air passages, like the nose, trachea and in the uterus and Fallopian tubes of females.
• Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord.
• Ciliated columnar epithelium in the pulmonary system is interspersed with goblet cells that secrete mucus to form a mucosal layer apical to the epithelial layer. The rowing-like action of epithelial cilia works in tandem with goblet cells to propel mucus away from the lungs, preventing particulate matter from causing infection.
• Hence the correct option is A.
