  2. features on occipital bone
    foramen magnum, occipital condyles
  3. temporal bones
    external auditory meatus, zygomatic process, mandibular fossa, styloid process, mastoid process
  4. sphenoid bone
    lesser & greater wings, sella turcica (Turk's saddle)
  5. Turk's saddle
    where the pituitary gland sits
  6. ethmoid bone
    crista galli, cribiform plate, superior nasal conchae
  7. crista galli
    anchor point for brain
  8. cribiform plate

  9. cranial sutures
    coronal, sagittal, squamosal, lambdoidal
  10. coronal suture
    between frontal and parietal plates
  11. sagittal suture
    between L&R parietal plates
  12. squamosal suture
    between parietal & temporal plates
  13. lambdoidal suture
    between parietal & occipital plates
  14. facial bones
    nasal, lacrimal, zygomatic, maxillary, palatine, mandibular, Vomer, inferior nasal conchae, orbit, nasal cavity, paranasal sinuses
  15. zygomatic arch
    made up of 2 parts - zygomatic process of the tempooral bone and temporal process of the zygomatic bone
  16. maxillary bones
    includes zygomatic process, infra-orbital foramens, palatine processes
  17. mandible
    includes mental foramens, mandibular foramens, coronoid process, mandibular notch, mandibular condyle
  18. paranasal sinuses
    include frontal, ethmoid & maxillary
  19. hyoid bone
    in throat - only bone that does not articulate with another bone
  20. vertebral column regions
    cervical, thoracic, lumbar & sacral
  21. spinous process points
