| Latin: | ligamentum atlantoaxialis posterius |
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis.
It supplies the place of the ligamenta flava, and is in relation, behind, with the obliqui capitis inferiores.
