The upper jaw is formed by how many bones?

Explanation:
The upper jaw is formed by two bones. Each side develops as its own maxilla and they fuse together along the midline at the intermaxillary suture to create the complete upper jaw and most of the hard palate. So, even though the palate’s rear portion involves the palatine bones, the upper jaw itself is made from two maxillary bones.
