Detailed explanation-1: -Pivot joint is a synovial joint in which the ends of two bones connect. In this joint, a cylinder-shaped bone rotates inside another ligament that forms a ring around the joint. The joint between the atlas and the axis which is right under the skull, allows the turning of the head from side to side.
Detailed explanation-2: -Pivot joints consist of the rounded end of one bone fitting into a ring formed by the other bone. This structure allows rotational movement, as the rounded bone moves around its own axis.
Detailed explanation-3: -Allow a circular movement – this is how ball and socket joints work: for example, the shoulder. Allow rotation without displacing the bones: for example, the head as it turns from side to side swivels the cervical vertebrae on top of one another.
