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]
Anatomy
The membrane broadens superiorly.[1]
Structure
The membrane consists of two laminae - superficial and deep.[2]
The superficial lamina broadens superiorly before attaching onto the superior/internal surface of the basilar part of occipital bone superior to the foramen magnum, here blending with the cranial dura mater.[2]
The deep lamina consists of a strong medial band which extends superiorly to the foramen magnum, and of two lateral bands which superiorly reach and blend with the articular capsules of the atlanto-occipital joint.[2]
Relations
The membrane situated is posterior/deep to the transverse ligament of the atlas; the two are separated by a thin intervening layer of loose areolar connective tissue, and sometimes by a bursa.[2]
The membrane is situated anterior/superficially to the spinal dura mater (which is firmly attached to the tectorial membrane).[3]
