Mascella
Mascella is a term used in Italian to refer to the jawbone, the central structure of the face that supports the teeth and shapes facial form. In human anatomy the jaw comprises two main bones: the maxilla, or upper jaw, and the mandible, or lower jaw.
The maxilla forms the upper dental arch and contributes to the orbital floor, nasal cavity walls, and
Both jaws contain alveolar processes that bear the teeth and protect important neural and vascular structures.
Developmentally, the upper and lower jawbones arise from neural crest cells, forming largely through intramembranous ossification.
Clinically, mascella injuries commonly occur with facial trauma and can affect chewing, speech, or occlusion. Disorders
