Aus Dornheim Anatomy
Atlas and axis together with the base of the skull form the upper and lower cervical joints. The connection between the occipital bone and the first cervical vertebra is the upper cervical joint. This connection is surrounded by a loose joint capsule and is held in place by ligaments between the occipital bone and the anterior and posterior arches of the atlas. This creates a range of motion of the joint of about 20° (forward and backward).
