Question: 1 / 400

Does the wrist joint consist of the ends of the radius and ulna with the carpal bones?

True

The statement is true because the wrist joint, known as the radiocarpal joint, is formed by the distal ends of the radius and the proximal row of carpal bones. The radius sits on the thumb side of the forearm, while the ulna is located on the pinky side. Although the ulna does not directly participate in wrist movement—due to the presence of an articular disc that separates the ulna from the wrist—the radius is crucial in connecting the forearm to the carpal bones. The carpal bones, which consist of eight small bones arranged in two rows, work alongside the radius to facilitate a wide range of wrist movements, including flexion, extension, and circumduction. Thus, it is accurate to state that the wrist joint includes the ends of the radius and ulna with the carpal bones, establishing their integrative role in wrist function and movement.
