Wrist Joint
The wrist joint, also known as the radiocarpal joint, is a complex joint that connects the forearm to the hand. It's a synovial joint that provides a wide range of motion, including
Types of Motion
- Flexion : Bending the wrist downward.
- Extension : Straightening the wrist upward.
- Abduction : Moving the wrist away from the midline of the body.
- Adduction : Moving the wrist toward the midline of the body.
- Circumduction : Moving the wrist in a circular motion.
- Rotation : Rotating the wrist clockwise or counterclockwise.
Anatomy
- Radius and Ulna : The two bones of the forearm that form the wrist joint.
- Carpals : The eight small bones of the wrist.
- Ligaments : Connective tissue that holds the bones together.
- Tendons : Connective tissue that attaches muscles to bones.
- Synovial membrane : A thin layer of tissue that produces synovial fluid, which lubricates the joint.
