Anatomical terminology

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]

A: Anterior atlantooccipital membrane

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]
