Posterior atlantoöccipital membrane
|Posterior atlantoöccipital membrane|
|Posterior atlantoöccipital membrane and atlantoaxial ligament. (Posterior atlantoöccipital membrane is topmost gray region at center.)|
|Latin||membrana atlantooccipitalis posterior|
|Gray's||subject #74 296|
The posterior atlantoöccipital membrane (posterior atlantoöccipital ligament), broad but thin, is connected above, to the posterior margin of the foramen magnum; below, to the upper border of the posterior arch of the atlas.
The free border of the membrane, arching over the artery and nerve, is sometimes ossified.
The membrane is in relation, behind, with the Recti capitis posteriores minores and Obliqui capitis superiores; in front, with the dura mater of the vertebral canal, to which it is intimately adherent.
