Structure

The atlantooccipital joint is surrounded by a joint capsule and is composed of a fibrous layer and synovial membrane. The capsule is composed of tough interwoven fibers and tends to be looser and slacker to facilitate the variety of movements associated with this joint.

Anatomical Relations

The fibrous layer of the atlantooccipital joint attaches along the margins of the articular surfaces, thus, enveloping them. These are the superior articular surfaces of the lateral mass of the atlas and the occipital condyles. The condyles are positioned on both sides of foramen magnum.

The fibrous layer blends with the anterior longitudinal ligament on their anteromedial aspects and with the posterior atlantooccipital membrane posteriorly.

Function

The fibrous layer adds and maintains the stability of the atlantooccipital joint. It restricts excessive movements of the articulating surfaces by tightening as they move.
