Human Anatomy

  1. body
    weight bearing portion
  2. vertebral foramen
  3. superior articular facet
    concave surface on superior, posterior
  4. inferior articular facet
    concave surface inferior to superior articular facets
  5. transverse process
    extends laterally from posterior of body
  6. spinous process
    extends back from posterior side
  7. intervertebral foramen
    hole between vertebrae
  8. cervical vertebrae
    relatively small, function is to support the head and allow for its movements
  9. C1/ atlas
    cervical vertebra: top of vertebral column, supports head
  10. C2/ axis
    cervical vertebra: prominent anterior knob, allows rotation
  11. dens/ odontoid process
    cervical vertebra: only on C2, projects into vertebral foramen of C1
  12. bifid spinous process
    cervical vertebra: protruding cleft point, bifid = cleft
  13. transverse foramen
    cervical vertebra: holes in transverse process
  14. thoracic vertebra
    correspond to the 12 pairs of ribs attached to them
  15. transverse coastal facet
    thoracic vertebra: shallow, cup-like facet at the anterior end of transverse process
  16. costal demifacet
    thoracic vertebra: pairs of facets for ribs closest to body of vertebra
  17. lumbar vertebra
    thick, stout, body and blunt, squarish spinous process
  18. sacral vertebra
    begin to fuse around age 16, and are usually fully fused into a single bony plate by age 26
  19. sacrum
    forms the posterior wall of the pelvic cavity and protects the organs within
  20. anterior sacral foramina
    four pairs of holes in the anterior side of the sacrum for nerves to pelvic organs
  21. posterior sacral foramina
    four pairs of holes in the posterior side of the sacrum to gluteal region and lower limbs
  22. sacral promontory
    supports body of L5 at proximal end
  23. auricular surface
    ear-shaped region of the sacrum that articulates with the hip bone
  24. coccygeal vertebra
    form tail bone
