Anatomical terminology

The posterior atlantooccipital membrane (posterior atlantooccipital ligament) is a broad but thin membrane[1][2]: 99  extending between the posterior margin of the foramen magnum above, and posterior arch of atlas (first cervical vertebra) below. It forms the floor of the suboccipital triangle.

The membrane helps limit excessive movement of the atlanto-occipital joints.[2]: 99
