Which type of papillae cover the DORSUM of the tongue (most numerous)?
Show answer and explanation
Correct answer: B. Filiform papillae
- A. Circumvallate (vallate) papillae are large, form a V-shape on the posterior tongue (only ~7-12), and are associated with taste buds.
- B. Correct. Filiform papillae are the most numerous type, covering the entire dorsum of the tongue. They are thread-like, whitish, and contain no taste buds — they provide texture and mechanical function. A photo of a normal tongue showing these thread-like projections indicates filiform papillae.
- C. Fungiform papillae are red mushroom-shaped papillae scattered across the anterior dorsum — they contain taste buds but are fewer than filiform.
- D. Foliate papillae are vertical folds on the lateral tongue edges.
