In the lateral parts of occipital bone, behind either condyle is a depression, the condyloid fossa, which receives the posterior margin of the superior facet of the atlas when the head is bent backward; the floor of this fossa is sometimes perforated by the condyloid canal (or condylar canal), through which an emissary vein passes from the transverse sinus.
