  1. Group 2Bones of the skull Fatin, Aishah, Zafirah, Laila, Masyitah, Amalina, Aimi

  2. Bones of the Skull

  3. Mandible 1 Vomer 2 Inferior nasal conchae 2 Lacrimal bones 2 Maxillae 2 Nasal bones Palatine bones 2 Zygomatic bones 1Ethmoid bone Frontal bone 1 Occipital bone Parietal bones Sphenoid bone Temporal bones

  4. FACIAL BONES

  5. CRANIAL BONES

  6. ADDITIONAL SKULL FEATURES • Major sutures • Paranasal sinuses • Hyoid bone

  7. Major Sutures

  8. Functions

  9. Maxilla & Mandible

  10. Maxilla • Forms the majority of the skeleton of the face and the upper jaw • Contains the maxillary sinus • Articulates with the frontal, sphenoid, nasal, vomer, and ethmoidbones; inferior nasal concha, palatine, lacrimal, and zygomatic bones; and septal and nasal cartilages

  11. Mandible • Forms the lower jaw • Described as horseshoe shaped • All muscles of mastication attach to the mandible • Consists of body of mandible, ramus, coronoid process, condylar process, alveolar process

  12. Lacrimal & Nasal bone

  13. Lacrimal Bone • Small and rectangular in shape • Very thin and fragile • Forms a small portion of medial wall of the orbit • Articulates with frontal process of the maxilla, orbital plate of the ethmoid bone, frontal bone and inferior nasal concha • The region that articulates with the frontal process of the maxilla forms the lacrimal fossa →the location of the lacrimal sac • The inferior part of the lacrimal forms a small portion of the lateral wall of the nasal cavity

  14. Nasal Septum • Septal Cartilage • Ethmoid bone • Vomer

  15. Base of Nasal Cavity • Maxilla – Palatine Process of Maxilla • Palatine Bone – Horizontal Plate of Palatal Bone

  16. Posterior Border of Nasal Cavity

  17. Superior Border of Nasal Cavity • Nasal Bone • Frontal Bone • Ethmoid Bone

  18. Lateral Border of Nasal Cavity • Ethmoid Bone • Lacrimal Bone • Inferior Nasal Concha • Palatine Plate

  19. Foramens of the Base of the Skull

  20. What is foramen? • A foramen (pl. foramina) is an opening. • Foramina allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.
