- Facies articularis superior

描述

The superior articular surface (superior facet)s are of large size, oval, concave, and approach each other in front, but diverge behind: they are directed upward, medialward, and a little backward, each forming a cup for the corresponding condyle of the occipital bone, and are admirably adapted to the nodding movements of the head. Not infrequently they arepartially subdivided by indentations which encroach upon their margins.
