The purpose of Vertebrae is…
Maintain posture

Purpose of vertebral disc
Absorb shock
What is a herniated disc?
Nucleus pulposus is leaking due to annular fibrosis no longer holding in nucleus.
What is Annular Fibrosis/?
Holds nucleus in place
“gate”
Kyphosis normal
Normal: 40 degrees
Normal Cervical lordosis (degrees)
30-35
Normal Lumbar Lordosis
45 degrees
Normal Sacral Kyphosis
Fused
Anterior Longitudinal ligament C2-Sacrum
- anterior surface of bodies, deep fibers that blend w discs
- 2x as strong as posterior
- adds stability to vertebral column
- limits extension or excessive lordosis in cervical + lumbar
Posterior Longitudinal Ligament C2-sacrum
- posterior surface of bodies, within vertebral canal
- thin in lumbar region
- reinforces posterior annulus fibrosis
- limits flexion
Interspinous
- between adjacent spinous process
- limits flexion
- vertebrae to vertebrae
Supraspinous C7-Sacrum
C7-sacrum
over interspinous (superficial)
along tips of spinous process
limits flexion
Ligamentum flavum
C2-sacrum
elastic + thick
limits flexion
Nuchal Ligament
Very thiccc
Holds neck- damage here affects whole body
alternate name for supraspinous and interspinous ligaments in neck
limits flexion
