Description
A broad, thin ligamentous sheet that connects the posterior rim of the foramen magnum to the superior border of the posterior arch of the atlas. The lateral aspects of the membrane blend with the posterior surfaces of the atlanto-occipital joint capsules. It is equivalent to the ligamentum flavum at other vertebral levels.
