Source-derived summary

The apical ligament of dens (or apical odontoid ligament) is a ligament that 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, which extends from the tip of the odontoid process on the axis to the anterior margin of the foramen magnum, being intimately blended with the deep portion of the anterior atlantooccipital membrane and superior crus of the transverse ligament of the atlas.

It is regarded as a rudimentary intervertebral fibrocartilage, and in it traces of the notochord may persist.

The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse.
