Pivot Joints Examples
In addition to the atlas-axis joint and radioulnar joints, there are a few other examples of pivot joints in the human body, including:
- The rotation of the skull is feasible due to pivot joints. The twisting movements of the bones of the forearm, against the upper arm, is due to pivot joints.
- The two bones are connected to each other, namely the radius and ulna that is located near the wrist by another pivot joint. With the help of two bones, they twist around each other by using a pivot joint.
- Without pivot joints, the skeleton of the physical body would lack flexibility and freedom of movement thus, making the movement of the skeleton quite stiff and rigid.
- Atlantooccipital joint: This joint is located between the skull and the atlas (C1). It allows for the nodding motion of the head.
- Intercarpal joints: These joints are located between the carpal bones in the wrist. They allow for a small amount of rotation of the wrist.
Pivot Joints: Definition, Diagram, & its Examples
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.
