Skull- occipital condyles

Inferior view

The occipital condyles are functionally important because they articulate with the superior articular facets of the atlas (C1). This joint functions as a hinge joint allowing flexion and extension of the head. When one shakes their head "no" the two bones move as one piece. Dr. J thinks these structures are shaped like the rockers of a rocking chair which facilitates the flexion and extension of the skull relative to the atlas. We find the hypoglossal canal in the lateral base of the occipital condyles, immediately superior to the condyles. This foramen is important as it transmits the hypoglossal nerve (XII). As the name implies, they are landmarks of the occipital bone.
