  1. extending from the skull to the pelvis, forms the bodys major axial support, surrounds and protects the delicate spinal cord while allowing spinal nerves to emerge from the cord
    vertebral column
  2. how many vertebrae are in the vertebral column
    24
  3. what are the two fused/composite bones
    sacrum and coccyx
  4. what is the fibrocartilage pads that separate the vertebrae
    intervertebral discs
  5. rounded central portion of the vertebra, which faces anteriorly in the human vertebral column
    body
  6. composed of pedicles, laminae, and a spinous process, it represents the junction of all posterior extensions from the vertebral body
    vertebral arch
  7. opening enclosed by the body and vertebral arch, a passageway for the spinal cord
    vertebral foramen
  8. two lateral projections from the vertebral arch
    transverse processes
  9. single medial and posterior projection from the vertebral arch
    spinous process
  10. paired projections lateral to the vertebral foramen that enable articulation with adjacent vertebrae
    superior and inferior articular processes
  11. the right and left pedicles have notches on their inferior and superior surface that create openings, the intervertebral foramina, for spinal nerves to leave the spinal cord between adjacent vertebra
    intervertebral formaina
  12. which vertebrae lacks the body and its lateral process contains large concave depressions on their superior surfaces that receieve the occipital condyle, say yes
    atlas
  13. which vertebrae acts as a pivot for the rotation of the atlas about, it bears a large vertical process called dens or odontoid process that serves as pivot point say no
    axis
  14. the body is some what heart shaped with two small articulating surfaces close to the origin of the vertebral arch
    costal facets
  15. is a composite bone formed from the fusion of five vertebrae
    sacrum
  16. is a remnant of the spinous process of the fused verterbrae
    median sacral crest
  17. winglike process, formed by fusion of the transverse processes, articulate laterally with the hip bones
    alae
  18. four ridges cross the anterior part of the sacrum
    sacral foramina
  19. the vertebral canal continues inside the sacrum
    sacral canal
  20. terminates near the coccyx via an enlarged opening
    sacral hiatus
  21. top of the sacrum important anatomical landmark for obsterticians
    sacral promontory
  22. is formed from the fusion of three or five small irregularly shaped vertebrae, tailbone
    coccyx
  23. which body is small, wide side to side
    cervical
  24. which body is heart shaped and bears costal facets
    thoracic
  25. which body is massive, kidney shaped
    lumbar
  26. which spinous process is short, bifid, projects directly posteriorly
    cervical
  27. which spinous process in long, sharp, projections inferiorly
    thoracic
  28. which spinous process is short blunt, projects directly posteriorly
    lumbar
  29. which verterbral foramen are triangular
    cervical and lumbar
  30. which vertebral foramen is circular
    thoracic
  31. which transverse processes contain foramina
    cervical
  32. which transverse processes bears facets for ribs
    thoracic
  33. which transverse processes are thin and tampered
    lumbar
  34. superior and inferior articulating processes: superior facets directed superoposteriorly; inferior facets directed inferoanteriorly
    cervical
  35. superior and inferior articulating processes: superior facets directed posteriorly; inferior facets directed anteriorly
    thoracic
  36. superior and inferior articulating processes: superior facets directed postmedially; inferior facets directed anterolaterally
    lumbar
  37. what movement includes flexion and extention; lateral flexion, rotation, the spine region with the greatest range of movement
    cervical
  38. what movement includes rotation; lateral flextion possible but limited by ribs and extension prevented
    thoracic
  39. what movement includes flexion and extension; some lateral flexion, rotation prevented
    lumbar
  40. consists of bony thorax, which is composed of the sternum, ribs, and thoracic vertebrae also costal cartilage
    thoracic cage
  41. typically a flat bone, is a resuly of the fusion of 3 bones, manubrium, body and xiphoid process
    sternum
  42. concave upper border of the manubrium can be palpated easily; generally it is at the level of the third thoracic vertebrae
    jugular notch
  43. is a result of the manubrium and body meeting at a slight angle to each other, so that the transverse ridge is formed at the level of the second ribs
    sternal angle
  44. the point where the sternal body and xiphoid process fuse, lies at the level of the ninth thoracic vertebrae
    xiphisternal joint
  45. how many pairs of ribs make up the thoracic cage
    12
  46. first seven pair of ribs are called
    true ribs
  47. the last five pair of ribs are called
    false ribs
  48. the last two pair of ribs are called
    floating ribs
