maxilla [mak-sil´ah] (L.)

one of two identical bones that form the upper jaw. The maxillae meet in the midline of the face and often are considered as one bone. They have been described as the architectural key of the face because all bones of the face except the mandible touch them. Together the maxillae form the floor of the orbit for each eye, the sides and lower walls of the nasal cavities, and the hard palate. The lower border of the maxilla supports the upper teeth. Each maxilla contains an air space called the maxillary sinus.
