Explaination :------

The atlanto-occipital joint (articulation between the atlas and the occipital bone) consists of a pair of condyloid joints. The atlanto-occipital joint is a synovial joint particularly hinge joint.

These joints act as a door hinge does, allowing flexion and extension in just one plane. The atlanto-occipital joint allows flexion and extension around the mediolateral axis, which give rise to the ordinary forward and backward nodding of the head.
