maxilla
Sign in to saveIn vertebrates, the maxilla (: maxillae ) is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw.
AI overview
The maxilla is the upper jaw bone in vertebrates, formed when two separate bones fuse together, and in humans it includes the hard palate at the front of the mouth. It matters because it provides the fixed upper structure of the jaw, contrasting with the movable lower jaw (mandible) that allows the mouth to open and close.
