Cervical intervertebral joints

• joint classification:

  Facet Joints (Zygapophyseal joints)

  • Facets sloped A-P which allows a large amount flexion and extension
  • Flexion (25)
  • Extension (85)
  • Lateral flexion 40
  • 50 rotation to each side
• joint classifcation:

  intervertebral disc

  • Secondary cartilaginous joint (symphysis)
  • Thick relative to height of vertebral body
• ligaments:

  . Ligamentum nuchae

  - Found only in the cervical region from C7 up to the skull

  - Continuation of the supraspinous ligament

  - Principle role is to increase surface area for muscle attachments

  Supraspinous ligaments

  Ligamentum flavum

  Interspinous ligaments

  Intertransverse ligaments
• movements:
