Implications of Pivot joints
- Forearm rotation: Rotation of the forearm is referred to as pronation and supination. Supination extends the hand’s palm whereas pronation reduces it. In this activities movements are essential like; turning as a screwdriver, turning as a doorknob.
- Head movement: In this joint movement allows in the position of left, right, or up and down. Although, neck is connected to head. Here, the atlantoaxial joint is a type of pivot joint which is between the first and second cervical vertebrae.
- Main purpose: Pivot joint function is to allow a body part to rotate around a single point, very similar to the rotation of a wheel because a pivot joint rotates around a single axis, it is often known as a ”rotary joint”.
- Muscles work: The muscles that link to the bones that comprise the pivot joints provide rotational movement.Their coordination is must So, that proper muscle control is essential to prevent injury and ensure smooth, controlled rotation around the joint.
- Damage Tendency: Excessive power, quick blows, and repeated tension can cause damage to pivot joints. These joints are particularly vulnerable to injury from disorders like inflammation, imbalanced muscles, and improper body mechanics.
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.
