The atlanto-occipital joint is the joint between the occipital bone of the skull and the first cervical vertebra, known as the atlas. The joint allows for flexion and extension, which are the primary up-and-down movements of the head. However, extension occurs more freely at this joint compared to flexion. Therefore, the correct answer is D) extension.
