This ligament is in relation, in front, with the Recti antici minores; hehiyid, with the odontoid ligaments. The posterior occipito-atlantal ligament (membrana atlanto-occipitalis posterior, posterior occipito-atloid ligament) (Figs. 226 and 228) is a very broad but thin membranous lamina intimately blended with the dura. It is connected, above, to the posterior margin of the foramen magnum; heloic, to the upper border of the posterior arch of the atlas. This ligament is incomplete at each side, and forms, with the groove in the upper surface of the posterior arch, an opening for the vertebral artery and suboccipital nerve. The fibrous band which arches over the artery and nerve sometimes becomes ossified. The ligaments are in relation, behind, with the Recti postici minores and Obliqui superiores; in front, with the dura of the vertebral canal, to which they are intimately adherent.

(Spalteholz.) The capsular ligaments (capsulae articulares) (Fig. 227) surround the condyles of the occipital bone, and connect them with the articular processes of the atlas; they consist of thin and loose capsules, which enclose the synovial membranes of the articulations. Synovial Membranes.—There are two synovial membranes in this articulation, one lining the inner surface of each of the capsular ligaments. These occasional!)' communicate with that between the posterior surface of the odontoid process and the transverse ligament. Movements.—The movements permitted i
