Description[edit | edit source]
Spans between the second cervical vertebra in the neck and the skull. It lies as a fibrous cord in the triangular interval between the alar ligaments.
Attachments[edit | edit source]
Arises from the apex of the odontoid process on the Axis to the anterior margin of the foramen magnum. It blendes with the deep portion of the anterior atlanto-occipital membrane and superior crus of the Transverse ligament of the atlas.
Function[edit | edit source]
Best described as a vestigial structure that offers no significant added stability to the craniocervical junction[1]. Has been found to be absent in 20% of people[1].
