Where the maxilla sits in the skeleton

The maxilla is one of the pair of bones forming the upper jaw. They hold the upper teeth and form the front of the hard palate, the floor of each eye socket and the sides of the nasal cavity. The two maxillae meet in the midline, and the body of each holds the maxillary sinus, the largest of the paranasal sinuses. The upper teeth sit in its alveolar process.
