  1. Chapter 7, part 2 The Axial Skeleton

  2. Figure 7.5 The Occipital and Parietal Bones Figure 7.5

  3. Figure 7.6 The Frontal Bone Figure 7.6

  4. Figure 7.7 The Temporal Bones Figure 7.7

  5. Figure 7.8 The Sphenoid Figure 7.8

  6. Figure 7.9 The Ethmoid Figure 7.9

  7. Facial bones • Inferior nasal conchae • Zygomatic bones • Lacrimal bones • Hyoid • Maxillary bones • Mandible • Palatine bones • Nasal bones • Vomer

  8. Maxillae • Largest facial bones • Form the upper jaw and most of the hard palate

  9. Figure 7.10 The Maxillary and Palatine Bones Figure 7.10

  10. Palatine and Nasal Bones • Palatine bones • Small “L” shaped bones • Form the posterior hard palate and floor of the nasal cavity • Nasal bones • Superior border of external nares

  11. Vomer, Zygomatic and Lacrimal bones • Vomer • Inferior portion of the nasal septum • Zygomatic bone • Temporal process articulates with zygomatic process of temporal bone • Lacrimal bones • Smallest bones of the face • Sit medially in orbit

  12. Figure 7.11 The Smaller Bones of the Face Figure 7.11

  13. Mandible and Hyoid bones • Mandible • Bone of the lower jaw • Hyoid • Suspended by stylohyoid ligaments • Supports the larynx

  14. Figure 7.12 The Mandible and Hyoid Bones Figure 7.12a

  15. Figure 7.12 The Mandible and Hyoid Bones Figure 7.12b, c

  16. The orbital and nasal complexes • Seven bones in the orbital complex • Nasal complex = bones that enclose the nasal cavities and paranasal sinuses

  17. Figure 7.14 The Orbital Complex Figure 7.14

  18. Skulls of infants and children • Fontanels permit skulls of infants and children to continue growing
