Frontal bone  This is a flat bone that makes up our forehead. It also forms the upper portion of the eye sockets. It forms a joint with the parietal bones that allow movement.

Parietal bones  This is a pair (2 bones) of flat bones located on either side of your head, behind the frontal bone.

Temporal bones  This pair (2 bones) of irregular bones are located under each parietal bone.

Occipital bone  This is a flat bone located in the very back of your skull. It has an opening that allows your spinal cord to connect to your brain.

Sphenoid bone  This is an irregular bone that sits below the frontal bone. It helps form the base and lateral sides of the skull in combination with the orbital floor.

Ethmoid bone  This is a single irregular porous bone located in front of the sphenoid bone. It makes up part of our nasal cavity.

Zygomatic This is a paired, irregular bone often referred to as the cheekbone.

Maxillary The two maxillae, or maxillary bones, fuse to form the upper jaw; all facial bones except the mandible join the maxillae; thus, they are the main or “keystone” bones of the face; the maxillae carry the upper teeth.

Nasal bones Two slender rectangular bones positioned in the midface. At their junction, they form the bridge of the nose.

Vomer This is a small, thin, plow-shaped bone that divides the nasal cavity.

Palatine These paired L-shaped bones form the rear of the hard palate and part of the wall and floor of the nasal cavity.

Inferior nasal conchae The lower bones in the nasal cavity. They are thin, curved bones projecting medially from the lateral walls of the nasal cavity.

Lacrimal These are the smallest bones of the face. They are finger-sized bones; each lacrimal bone has a groove that serves as a passageway for tears.

Mandible  The mandible, or lower jaw, is the largest and strongest bone of the face; it joins the temporal bones on each side of the face, forming the only freely movable joints in the skull.

Teeth There are 20 primary teeth containing the hardest substances in the human body: enamel. Enamel is mostly made of calcium phosphate, a rock-hard mineral and helps in chewing and speech.
