  1. Lecture 6.4: Skeletal System

  2. The Skull • AKA: The Cranium • Protects our brain • Gives us our senses

  3. Frontal Bone • Forehead • Orbits—spaces for eyes • Frontal sinuses—air-filled chambers • Lighten bone • Produce mucus for nasal cavity

  4. Figure 6.10

  5. Parietal Bone (Paired) • Posterior to frontal bone • Sagittal suture—locks 2 bones together • Coronal suture--locks parietal to frontal

  6. Figure 6.15b

  7. Occipital Bone • Most posterior • Lambdoid Suture—locks occipital with parietal • Foramen magnum—where spinal cord passes

  8. Figure 6.10

  9. Temporal Bone (Paired) • Below parietal • Squamous suture—connects parietal to temporal

  10. Figure 6.10

  11. Sphenoid Bone • Part of floor of cranium • Unites cranium and facial bones • Sellaturcica—depression that houses pituitary gland

  12. Figure 6.12a

  13. Ethmoid Bone • Anterior to sphenoid • Medial eyes and roof and sides of nasal cavity • Nasal septum—divides nose into left/right sides

  14. Figure 6.12a
