transverse ligament of the atlas

Also found in: Wikipedia.

trans·verse lig·a·ment of the at·las

thick, strong, centrally flattened band spanning the vertebral foramen of the atlas as it extends from the medial aspect of one lateral mass to the other, passing dorsal to the dens with which it articulates; it forms the dorsal portion of the opening for the dens, tightly embracing its neck. It forms a part of the "cross-bar" of the cruciform ligament of the atlas.
See also: cruciate ligament of the atlas.

transverse ligament of the atlas

a thick, strong ligament stretched across the ring of the atlas, holding the dens against the anterior arch. The transverse ligament divides the circular opening of the atlas into posterior and anterior parts. The posterior part transmits the spinal cord and its membranes; the anterior part contains the dens.
