Detailed explanation-1: -pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament.

Detailed explanation-2: -Pivot joints are types of synovial joints that allow one bone to rotate over another. for example, the joint present on the back of your neck is are two pivot joints which allows you to move your head up and down or left and right.

Detailed explanation-3: -At a pivot joint, one bone rotates in relation to another bone. This is a uniaxial joint, and thus rotation is the only motion allowed at a pivot joint.

Detailed explanation-4: -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-5: -Two examples of pivot joints are the pivot joints in the neck, that allows the head to rotate and the pivot joints between radius and ulna help in rotating the forearm.
