The human skull is the part of the skeleton that supports the structures of the face and forms a cavity for the brain. The skull supports the musculature and structures of the face and forms a protective cavity for the brain. The skull is formed of several bones which, with the exception of the mandible, are joined together by sutures—synarthrodial immovable joints. The adult human skull is comprised of twenty-two bones which are divided into two parts of differing embryological origin: the neurocranium and the viscerocranium.
The viscerocranium face includes these bones: vomer, 2 inferior nasal conchae, 2 nasals, maxilla, mandible, palatine, 2 zygomatics, and 2 lacrimals. The viscerocranium or facial bones supports the soft tissue of the face. The viscerocranium consists of 14 individual bones that fuse together. However, the hyoid bone, ethmoid bone, and sphenoid bones are sometimes included in the viscerocranium. The two zygomatic bones form the cheeks and contribute to the orbits.

Palatine Bones are facial bones that are located between the palatine processes of the maxillary bones and the pterygoid processes of the sphenoid bones. The two maxilla or maxillary bones maxillae, plural form the upper jaw L.
