Functions of Pivot Joints
It plays a role of movements in the body’s functions, Let’s see the pivot joints’ functions as follows:
- It allows movement where a cylinder-shaped bone is rotating inside the ring-shaped bone on a single axis. Like; In the neck, Skull moves on the upper point of the neck bone in the position of left, right, or up and down.
- They are quite stable in nature, For example, a thick syndesmosis holding the ulna and radius together supports the radioulnar joints that are inversely in relationship to joint stability and movement.
- They mostly coordinate with other joints, and muscles for creating movements. E.g. In this process, forearm works with the elbow joint and muscles to get movements such as holding, pushing, or pulling.
- Pivot joints are adapted to adjust various loads and pressures. It is crucial for joint-stressing exercises like weightlifting and athletics, where the joints must endure high degrees of strain and stress.

Pivot joints are those joints that show movement in a single direction. Joints are points of contact between bones. The joint acts as a fulcrum that helps in dispersing the force generated by the muscles. The Pivot joint is a type of Synovial joint that is characterized by the presence of synovial fluid. Other types of Synovial joints are Ball and Socket Joints, Hinge Joints, and Gliding Joints. One example of the pivot joint is the joint between the atlas and the axis. Another Pivot joint in the human body is made of the bones in the wrist.
