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

The Facial Bones of the Skull
 The Maxillae
 Functions of the maxillae
 Support upper teeth
 Form inferior orbital rim
 Form upper jaw and hard palate
 Contain maxillary sinuses (largest sinuses)

5. Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
The Facial Bones of the Skull
 Articulations of the Maxillae
 Frontal bones
 Ethmoid
 With one another
 All other facial bones except the mandible

The Facial Bones of the Skull
 Marks of the Maxillae
 Orbital rim:protects eye and orbit
 Maxillary sinuses: to lighten bone

The Facial Bones of the Skull
 The Nasal Bones
 Functions of the nasal bones
 Support the bridge of the nose
 Connect to cartilages of the distal part of the nose (external
nares)
 Articulations of the nasal bones
 With other nasal bones
 Ethmoid
 Frontal bones
 Maxillae

9. Copyright © 2009 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
The Facial Bones of the Skull
 The Zygomatic Bones
 Functions of the zygomatic bones
 Contribute to the rim and lateral wall of the orbit
 Form part of the zygomatic arch
 Articulations of the zygomatic bones

The Facial Bones of the Skull
 The Lacrimal Bones
 Functions of the lacrimal bones
 The smallest facial bones
 Form part of the medial wall of the orbit
 Articulations of the lacrimal bones
 Frontal bone
 Maxillae
 Ethmoid

The Facial Bones of the Skull
 The Mandible
 Functions of the mandible
 Forms the lower jaw
 Articulations of the mandible
 the temporal bones

 Attaches muscles of the larynx, pharynx, and
tongue

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 unfused sutures in the infant skull
 Allow the skull to flex during birth
