1. Facial Bones Nasal Bones (2) Maxilla Bones (2) Lacrimal Bones (2) Zygomatic Bones (2) Palatine Bones (2) Inferior Nasal Conchae (2) Vomer Mandible

2. Nasal Bones Together, form the bridge of the nose

3. MaxillaBones Form: –Upper jaw –Anterior roof of mouth (hard palate) –Floor of eye socket(orbit) Contain sockets for upper teeth

4. Maxilla Bones Maxillary Sinuses: largest sinuses

5. Lacrimal Bones Front part of the medial orbit wall Between the maxilla and ethmoid bones House nasolacrimal ducts (tear ducts)

6. Zygomatic Bone Forms: – prominence of cheek –Part of lateral wall and floor of orbit

7. Palatine Bones Form: –Posterior hard palate –Floor & lateral wall of nasal cavity –Floor of orbit Affected with a cleft palate

8. Inferior Nasal Conchae Projections in lateral wall of nasal cavity Support mucous membranes –Warm, moisten, filter air Increase surface area

9. Vomer Thin flat bone in medial plane Along with ethmoid, forms the nasal septum

10. Mandible Lower Jaw Largest and strongest bone of face Only movable bone of skull Houses lower teeth

11. Mandible Mandibular Condyle: articulates with temporal bone Coronoid Process: site of attachment for mastication muscles- protrudes when jaw is depressed

12. Fontanelles membraneous spaces between the skull bones of the fetus and infant where ossification is not complete. Permit compression at birth Skull bones are thin and flexible, so less easily broken aka “soft spot” in infants

13. Fontanelles Complete ossification of fontanelles occurs by age 26 –Posterior closes by ~2 months –Sphenoid closes by ~ 3 months –Mastoid closes by ~ 1 year –Anterior closes ~end of 2 nd year of life
