  2. Anterior tubercles of the cervical vertebrae
  3. Anterior longitudinal ligament of the cervical vertebrae
  4. Posterior longitudinal ligament of the cervical vertebrae
A

Anterior surfaces of the bodies of the cervical vertebrae. Prevertebral muscles fleck the neck and can also flex the skull at the atlantooccipital joint.
