Answer 1

The joint formed by the axis and atlas that permits the "no" shaking of the head is a pivot joint. They are synovial joints where the articulating surfaces are molded in a manner similar to a pivot and only allow movements in the longitudinal axis and the only permitted movements are the movements of lateral rotation and medial rotation.
