The human body has two main pivot joints.
Pivot joints, or rotary joints, allow for rotational movement around a single axis. In the human body, the most notable examples are found in the neck and the forearm. The first and second cervical vertebrae, known as the atlas and axis, respectively, form a pivot joint that enables the head to turn from side to side. Similarly, the joint between the radius and ulna in the forearm, which allows for the rotation of the wrist, is another example of a pivot joint.
These joints are essential for a variety of movements and play a key role in providing flexibility to our skeletal structure.
