The atlanto-occipital joint primarily allows which movement?

• A. Rotation
• B. Nodding movements
• C. Abduction
• D. Pronation

Answer: (B)

The main movement at the atlanto-occipital joint is nodding the head. This joint, where the skull sits on the atlas (the first neck vertebra), is structured to allow flexion and extension—think yes rather than no. It’s a condylar joint that enables the head to tilt forward and back with a primary range of motion in that direction. Rotation of the head, the other common head movement, happens mainly at the atlanto-axial joint between the atlas and the second cervical vertebra. Abduction and pronation are not characteristic movements of this joint.
