Anatomical terminology

The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/[1]broad, strong band[2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous).[3][1][2]

It attaches inferiorly onto (the posterior aspect of[2]) the body of axis.[3] It broadens superiorly. Superiorly, the membrane extends deep to the median atlanto-axial joint and its associated ligaments, then through the foramen magnum into the cranial cavity[1] where it ends by attaching onto the basilar part of occipital bone superior to the foramen magnum.[3]
