A mother asks about a normal structure she notices under her daughter's tongue. No photo is provided. What is most likely being described?
Show answer and explanation
Correct answer: B. Normal sublingual venous supply
The sublingual venous plexus (prominent veins on the ventral tongue/under tongue floor) is a common normal finding that parents may notice. Sublingual varicosities are normal, blue-purple vessels visible under the tongue. Source answer: 'venous supply.'
- A. Wharton's duct opening is at the sublingual caruncle — a specific anatomical point, not a vascular structure.
- B. CORRECT. Normal sublingual venous supply — prominent blue-purple veins visible under the tongue. Normal variant.
- C. Plica fimbriata are normal mucosal folds on ventral tongue — folds, not vessels.
- D. Ranula is a mucus retention cyst — pathological, blue/translucent swelling, not a normal finding.
