The maxilla is a paired bone in the human skull that forms the upper jaw. It plays a crucial role in supporting the teeth, forming the roof of the mouth, and contributing to the structure of the face. The maxilla also contains the maxillary sinuses, which are air-filled spaces that help lighten the weight of the skull and contribute to voice resonance. In addition to its structural functions, the maxilla connects with several other bones in the skull, including the nasal bones, zygomatic bones, and palatine bones. This connectivity is essential for the overall shape and function of the face, as well as for processes like chewing and speaking.
