The upper jaw is formed by which bone?

Explanation:
The upper jaw is formed by the maxilla. This bone holds the upper teeth in the alveolar process and makes most of the hard palate, as well as contributing to the floor of the nasal cavity and part of the orbit. The other bones have different roles: the zygomatic bone forms the cheek and part of the orbit, the palatine bone forms the back part of the hard palate, and the frontal bone shapes the forehead and the upper part of the eye sockets.
