What is the name of the upper jaw bone?

The upper jaw bone is called the maxilla. This bone plays a crucial role in the structure of the face, housing the upper teeth and forming parts of the eye sockets and nasal cavity. It is a paired bone, meaning that there are two maxilla bones—one on each side of the face—joined together at the midline.

The maxilla supports important functions such as chewing, speaking, and overall facial aesthetics. It is also integral in the formation of the palate (the roof of the mouth), which separates the oral cavity from the nasal cavity, facilitating proper breathing and swallowing.

In contrast, the mandible is the lower jaw bone, while the nasal bone is part of the bridge of the nose, and the temporal bone is located at the sides of the skull. Each of these bones plays an essential role in the anatomy of the face and skull, but none is referred to as the upper jaw bone.
