Anatomical terminology [ edit on Wikidata]

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]
