The anterior atlantooccipital membrane (anterior atlantooccipital ligament^{[citation needed]}) is a broad, dense^[1] membrane extending between the anterior margin of the foramen magnum (superiorly), and (the superior margin of^[2]) the anterior arch of atlas (inferiorly).^[3]^[2]^[1]

The membrane helps limit excessive movement at the atlanto-occipital joints.^[3]

Anatomy

Structure

It is composed of broad, densely woven fibers; especially towards the midline^[3] where the membrane is continuous medially with the anterior longitudinal ligament.^[3]^[1] It is innervated by the cervical spinal nerve 1.^[2]

Relations

Medially, it is continuous with the anterior longitudinal ligament.^[3]^[1]

Laterally, it is blends with either articular capsule.^[1]

This membrane is in relation in anteriorly with the rectus capitis anterior muscles, and posteriorly with the alar ligaments.^{[citation needed]}
