below to the body of the axis near the base of the odontoid process, and above to the lateral mass of the atlas near the transverse ligament.
The Anterior Atlantoaxial Ligament (Fig. 304).This ligament is a strong membrane, fixed, above, to the lower border of the anterior arch of the atlas; below, to the front of the body of the axis. It is strengthened in the middle line by a rounded cord, which connects the tubercle on the anterior arch of the atlas to the body of the axis, and is a continuation upward of the anterior longitudinal ligament. The ligament is in relation, in front, with the Longi capitis.

The Posterior Atlantoaxial Ligament (Fig. 305).This 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.
The Transverse Ligament of the Atlas (ligamentum transversum atlantis) (Fig. 306, 307, 308).The transverse ligament of the atlas is a thick, strong band, which
