Human Skull - occipital condyle (of occipital bone)

The probe is pointing to an occipital condyle on the underside of the skull (base). The two occipital condyles are large rounded kidney-shaped projections of occipital bone that are located contralateral to the foramen magnum and that articulate with the superior facets of the "Atlas" (C1) cervical vertebra.

Bone Terms:
condyle - a smooth, articulating surface (a joint) that slightly curved, typically. It is often covered with articular cartilage that is smooth and "slippery" to reduce friction between bone surfaces during movement.
