Which bone forms the upper jaw?

• A. Maxilla
• B. Zygomatic Bones
• C. Mandible
• D. Nasal Bones

Answer: (A)

The upper jaw is formed by the maxilla. This bone sits at the center of the face, carries the upper teeth, and helps shape the floor of the eye socket and the roof of the mouth (forming the hard palate) with the palatine bones. It also contains the maxillary sinuses and contributes to the nasal cavity. The other bones have different roles: the zygomatic bones are the cheekbones, the mandible is the lower jaw, and the nasal bones form the bridge of the nose. Knowing the maxilla’s location and connections helps with safe, effective facial massage around the midface.
