Airfilled spaces: Sinuses are air filled spaces in the head that have several proposed functions: 1. They serve as shock absorbers in cases of head trauma 2. Lighten the skull 3. Humidify and filter the air while also producing mucus 4. Play a role in vocal resonance.
The head contains 4 paired sinus cavities: maxillaries (cheek) under the eyes, ethmoids(between the eyes), frontals (above the eyes) and sphenoid.
