  1. What are the functions of ligaments?
    • Limit motion
    • assist maintaining normal curves
    • enhance stability
    • proprioception - spinal ligaments contain mechanoreceptors & provide information on posture, ligament stretch
  2. Ligamentum flavum
    • found between lamina
    • highly elastic: "yellow ligament"
    • limits flexion protecting discs from compression
    • posterior to spinal cord
    • hyperextension buckle ligament and pinch spinal cord
  3. Supraspinous ligament
    • extends between adjacent spinous spinous (from the sacrum to C7)
    • limits flexion
    • lumbar spine: typically 1st to rupture with extreme flexion
  4. Interspinous ligament
    • extend between adjacent spinous processes (from sacrum to C7)
    • limits flexion
    • lumbar spine: typically 1st to rupture with extreme flexion
  5. ligamentum nuchae
    • thickening of supraspinous and interspinous in c-spine
    • support to head and neck (passive tension)
    • accounts for difficulty palpating spinous process in mid to upper cervical region
  6. intertransverse
    • adjacent transverse processes
    • limits contralateral lateral flexion
  7. anterior longitudinal ligament
    • anterior surface vertebral bodies (sacrum to C2)
    • widens caudually
    • blends with and reinforces adjacent portion intervertebral discs
    • axial stability
    • limits extension or excessive lordosis in cervical/ lumbar region
    • stronger than posterior longitudinal ligament
  8. posterior longitudinal ligament
    • within vertebral canal anterior to spinal cord
    • posterior surface of vertebral bodies
    • slender lumbar limits ability to restrain disc bulge
    • axial stability
