  1. Sphenoid
    Cranial bone that can be seen in the eye socket-the main section inside eye socket

    Also can be seen from the side-it is slightly anterior to the temporal bone

    Has the optic canal
  2. Ethmoid
    Is the bone that separates the nasal cavity from the brain. 

    It can be seen (anterior) directly medial to the sphenoid bone.
  3. Maxilla
    The upper half of mouth
  4. Zygomatic Bone
    It is lateral to maxilla and nasal bones.  It is the inferior/lateral bone of the eye socket. 

    From the side, it also contain the zygomatic arch (cheek bone)

    A paired bone
  5. Palatine
    Deep to the maxilla, it is the back bone of the roof of mouth. 

    Also a paired bone
  6. Lacrimal
    Smallest bone of the face.

    Contains the lacrimal groove
  7. Inferior nasal concha
    bone in the nose that structures the scroll like pathway of the sinus
  8. Mandibular Condyle
    The condyle of the mandible that is the most posterior.

    The bone that enables us to open/close mouth
  9. Coronoid process
    The process of the mandible that connects to the masseter and temporalis muscles for mastation
  10. Vomer
    One of the few unpaired bones of the face. 

    It is the bone in the nose closest to the jaw
  11. External Occipital Protuberance
    The bump on the back of skull.

    It attaches the trapezius muscle to the skull.  Larger in males.
  12. Nuchal lines
    Ridges on the occipital bone that provide attachment for neck muscles
  13. Mastoid process
    Bulge behind ear.

    Provides attachment for sternocleidomastoid muscles
  14. Styloid process
    A pointy projection under the ear. 

    It provides attachment for ligaments and muscles of the neck like the stylohyoid muscle and stylohyoid ligament.
  15. Foramen Magnum
    Largest opening in the skull.

    It is the opening of the vertebral canal to the brain.
  16. Jugular Foramen
    More posterior than the carotid canals, it is near the foramen magnum.  Lies between the temporal and occipital bones

    Provides a passageway for certain cranial nerves and the Sigmoid sinus (jugular vein).
  17. Carotid Canal
    In the temporal bone and more anterior to the jugular foramen. 

    Allows passage of the carotid artery and other cranial nerves
  18. Cervical Vertebra
    Contains Transverse Process: Opening of the transverse foramen (for vertebral artery) and it is most posterior of all vertebrae.  From a lateral view, you may be able to see the transverse foramen and it appears to be large.  7 of them

    Has a spinous process (flattened), articular facets, and body (smaller).
  19. Thoracic Vertebra
    Main unique feature is the coastal facet: the connection between the vertebra and ribs

    Has a medium sized body, and long transverse process.  (also, perhaps the image is incorrect, but there appears to be a missing upsidedown "U" on the bottom of lateral view)  12 of them
  20. Lumbar Vertebra
    Unique feature is the very large body (weight support). 

    It has a spinous process, transverse process (2 "arms" and facets.
  21. True Ribs
    The first 7 ribs that have a direct (with cartilage) connection with the sternum.
  22. False Ribs
    Ribs that do no connect with the sternum.
  23. Floating Ribs
    Bottom two ribs (4 total) that do not have either a direct or indirect connection with the sternum.
