What is the term for the facial bones that compose the massive upper jaw?

The term for the facial bones that compose the massive upper jaw is 'maxillary bones.' These bones are critical as they form the central part of the facial skeleton. Each maxilla (singular of maxillary) plays a role in forming the hard palate of the mouth, the floors of the orbits (eye sockets), and the sides of the nasal cavity. They also hold the upper teeth and are involved in processes such as facial structure and speech.

In contrast, the mandibular bones refer to the lower jaw, while zygomatic bones form the cheeks, and nasal bones are responsible for the shape of the nose. Understanding the specific roles and locations of these bones helps in comprehending their importance in both anatomy and functions related to the face.
