Craniovertebral Joints and Prevertebral Region - Laboratory Identifications

Identifications for Craniovertebral Joints

1. Anterior arch of the atlas
2. Posterior arch of the atlas
3. Superior articular facet of atlas (atlanto-occipital joint articulation)
4. Facet for dens of the atlas (atlanto-axial joint articulation)
5. Anterior and posterior synovial cavities of atlanto-axial joint
6. Transverse ligament of atlas - prevents posterior displacement of dens, component of cruciate ligament
7. Alar ligaments - from dens to margin of foramen magnum, limits rotation
8. Tectorial membrane - superior extension of posterior longitudinal ligament
9. Superior and Inferior longitudinal ligaments - vertical component of cruciate ligament
