|Anatomical terms of bone|
The maxilla (plural: maxillae //) is the upper jawbone formed from the fusion of two maxillary bones. The upper jaw includes the palate of the mouth. The two maxillary bones are fused at the inter maxillary suture. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis.
Sometimes as in bony fish, the maxilla is called the "upper maxilla", with the mandible being called the "lower maxilla". Conversely, in birds the upper jaw is often called the "upper mandible".
