What is the medical name for the fused bones of the upper jaw?

The medical name for the fused bones of the upper jaw is the maxillae. These bones form the upper jaw and are central to the structure of the face, playing a crucial role in functions such as chewing and forming facial contours. The maxillae support the upper teeth, help form the orbits of the eyes, and contribute to the nasal cavity structure.

In contrast, the mandible is the lower jawbone and is not fused, whereas the zygomatic bones are the cheekbones located laterally to the maxillae, and the nasal bones form the bridge of the nose. Understanding the specific anatomy of the maxillae is important in various medical and dental practices, as well as in trauma care, where injuries to these areas may affect both function and aesthetics.
