  1. vertebral components:
    • Vertebral canal·        
    • Lamina·        
    • Pedicle·        
    • Intervertebral foramen
  2. what are the borders of the intervertebral foramen...
    ant and inf:
    true superiorly:
    • disc (anterior and inferior),
    • vertebral body (superiorly),
    • pedicle (true superiorly)
    • the facet joints (posteriorly)
  3. what emerges thru each intervertebral foramen
    a spinal nerve
  4. Posteriorly there is a  set of boney plates   and projections that serve what 3 functions?
    • To protect the spinal cord
    • To give attachments to muscles and ligaments·        
    • To articulate with the adjoining vertebrae
  5. what encloses the spinal cord?
    The neural Arch
  6. The space that’s surrounded by the  arch and the vertebral body is called
    “The Vertebral Foramen”
  7. shape of the neural foramen:
  8. shape of the vertebra body:
  9. what forms the neural arch?
    2 lamina
  10. what is the mass of bone btwn the facets?
    Articular pillar
  11. what arises from the sides of the vertebral body as well as from the articular pillar?
  12. what passes thru the transverse foramen?
    vertebral artery
  13. what is the most mobile part of the spine? why?
    • cervical vertebra
    • in the axial pivot joint

    • Partly bc of the curved shape of their bodies which make flexion and extension easy·        
    • And partly bc of shallow slope of their articular processes -makes lateral flexion easy
  14. where does the most movement occur?
    atlantoaxial joint

    There is a greater degree of Intersegmental Movement occurring at the Atlantooccipital Joint and Atlantoaxial Joint because there    are no discogenic restrictions
  15. what type of joint is the atlantoaxial joint?
  16. movements that occur in the spine?
    • forward  and lateral flexion
    • ext
    • rotation -combo of rotation and lateral flexion
    • lateral flexion inhibits rotation
  17. what is the name for C1?
  18. does the atlas vertebra have a body?
  19. what is the name for C2?
  20. what hold the odontoid?
    • transverse ligaments
    • alar ligaments
  21. movements assoc with occipital-atlas-axis articulations:
    • rotation of the head (at atlantoaxial jts)
    • flexion, ext, lateral flexion (at atlantooccipital jts)
