  1. Cervical Spine Anatomy

  2. General Vertebral Anatomy • Body • Vertebral Arch • Pedicles • Laminae • Vertebral Foramen • Spinous Process • Facets • Superior Articulating Surface • Inferior Articulating Surface • Transverse Process • Intervertebral Foramen

  3. Distinguishing Features of Cervical Vertebrae • Transverse foramina • C1 transverse process • Spinous Processes • C6 and C7 • C3-C6 = bifurcate • None for C1 • Articulating Facets

  4. Atlas • 1st Cervical Vertabrae • Lack of Body • Superior Articular Foveae • Inferior Articulating Foveae • Fovea Dentis

  5. Axis • C2 • Dens • Rotation between skull and atlas

  6. C7 • Body • Spinous process • Transverse Foramina • Anterior element

  7. Articulations within cervical region • Lateral Atlantoaxial Joints • Superior facets and inferior facets of atlas • Flat and in transverse plance • Rotation • Side toward rotation • Side away from rotation • Median Atlantoaxial Joints • Dens of axis and anterior arch of atlas • Tectorial membrane • Cruciform ligament

  8. Articulations within cervical spine • Body-to-body articulation • Fibrocartilagenous Intervertebral Disk • Annulus fibrosis • Nucleus pulposis

  9. Articulations within cervical spine • Cervical facet joints • Parallel to frontal plane • 45 degrees to transverse plane • Rotation

  10. Ligaments within cervical spine • Ligamentum Nuchae • Interspinous Ligament • Ligamentum Flava • Posterior Atlanto-occipital membrane • Intertransverse Ligament

  11. Curvature of cervical spine • Lordotic Curve

  12. Cervical spine movement • Flexion/Extension • Atlanto-occipital • Rotation • Atlanto-axial joint
