Maxilla 上颌骨
（重定向自Upper jaw）
The maxilla (plural: maxillae /mækˈsɪliː/) 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.
