The tissue lining the true vocal cords is best described as which type of epithelium?

• A. Simple squamous
• B. Stratified squamous
• C. Pseudostratified ciliated columnar
• D. Transitional

Answer: (B)

The surface of the true vocal cords is best described as non-keratinized stratified squamous epithelium. This type provides multiple cell layers to protect against the repeated mechanical abrasion that occurs during speaking and singing, while remaining moist and flexible to allow smooth vibration. Simple squamous would be too thin to resist friction, and pseudostratified ciliated columnar epithelium is the type lining most of the respiratory tract where mucus traps particles, not the delicate, friction-prone surface of the cords. Transitional epithelium suits structures that stretch, like the bladder, not the vocal cords.
