Vertebral Column
Show Answers:

  1. How many vertebrae are there total?
    • 7 cervical
    • 12 thoracic
    • 5 lumbar
    • sacrum=5 fused
    • coccyx=4 fused

    33 Vertebrae total
  2. Which parts of the spine are concave and convex?
    • Anterior=convex
    • posterior=concave
  3. scoliosis
    latteral curvature of the spine
  4. kyphosis
    • hunchback
    • excessive curvature of the thoracic vertebrae
  5. Lordosis
    • swayback
    • excessive curvature of the lumbar region
  6. What is C1 called and what makes it unique?
    • Atlas
    • missing a body
  7. What is C2 called and what makes it unique?
    • Axis
    • Has an odontoid process (dens)
    • Blue=lamina
    • pink=body
    • yellow=vertebral foramen
    • green=pedicle
    • purple=transverse process
    • white=superior articulating facet
    • underneath white=inferior articulating facet
    • between green and purple=transverse foramen
    • also has spinous process and intervertebral foramen
  8. atlantooccipital joint
    condyloid joint where the atlas and the head come in contact
  9. atlantoaxial joint
    pivot joint where the atlas and the axis articulate
  10. What seperates the cervical vertebrae from the thoracic and lumbar vertebrae?
    cervical vertebrae have 3 foramina compared to one and they have bifurcated spinous processes
  11. What differentiates the thoracic vertebrae from the others?
    spinous process points down
  12. What differentiates the lumbar vertebrae from the others?
    big body and stubby spinous process
  13. What is the ligament that goes from the occipital protuberance to C7 called?
    ligamentum nuchae
  14. What are the two ligaments that run the whole length of the spine called and what are their functions?
    Anterior longitudinal ligament: front of the body of the vertebrae and limits extension of head (weaker)

    Posterior longitudinal ligament: back of the body of the vertebrae and limit head flexion and forms the spinal canal
  15. What movements are within the vertebral column?
    • lateal flexion
    • flexion
    • extension
    • hyperextension
    • rotation

    • joint to joint: not a lot of movement
    • overall: a lot of movement
  16. What is in between the vertebrae and what is included?
    • inervertebral disc
    • outside layer: annulus fibrosus: tough, dense, fibrous
    • inside layer: nucleus pulposus: jelly-like substance
  17. what is is called when the intervertebral disc slips?
    herniated disc
