What term describes one of the upper jaw bones that forms the majority of the upper face?

The term that describes one of the upper jaw bones which forms the majority of the upper face is the maxilla. The maxilla consists of two bones that fuse at the midline and are crucial for forming the upper jaw, the roof of the mouth, the lower part of the eye sockets, and the nasal cavity. Its prominence plays a significant role in overall facial structure and has important features that contribute to functions such as chewing and speaking.

The mandible refers to the lower jaw and is not involved in forming the upper part of the face. The palatine bones are located at the back of the oral cavity and contribute to the hard palate but do not form the majority of the upper face. The zygomatic bones, commonly known as the cheekbones, contribute to the facial structure but do not constitute the upper jaw. Thus, the maxilla is accurately identified as the bone that forms the majority of the upper face.
