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]
