Facial Bones
Superficial Facial Bones
Maxillae = maxillary bones
Lacrimal
Nasal
Zygomatic
Mandible

The Facial Bones of the Skull
The Maxillae
Functions of the maxillae

The Orbital Complex
Paranasal Sinuses
Air-filled chambers connected to the nasal
cavities
Lighten skull bones
Provide mucous epithelium (flushes nasal cavities)

Fontanelles
Fontanelles(sometimes spelled fontanels)
Are areas of fibrous connective tissue (soft spots)
Cover unfusedsutures in the infant skull
Allow the skull to flex during birth
