Quizplus · Accepted Answer

Paranasal sinuses are air-filled cavities located in bones of the face and cranium, including the frontal, ethmoid, sphenoid, and maxillary bones. These sinuses serve to lighten the skull, provide resonance to the voice, and produce mucus that moistens and cleans the nasal passages. The other options do not refer to air-filled cavities.
