Final answer:
The wrist joint is formed by the distal end of the radius and some carpal bones, not the ulna. While the ulna does contribute to the wrist joint, it does not directly articulate with the carpal bones, as its connection is indirect via a fibrocartilaginous pad.
Step-by-step explanation:
The statement about the wrist joint consisting of the ends of the radius and ulna bones of the forearm with the carpal bones of the hand is False. While it is true that the wrist joint includes the ends of the radius, it is not accurate to state that the ulna directly articulates with the carpal bones.
In detail, the wrist joint, also known as the radiocarpal joint, is formed by the articulation of the distal end of the radius and the carpal bones. However, only three carpal bones, specifically the scaphoid, lunate, and triquetrum, are directly involved in this articulation. The ulna, on the other hand, does not have a direct articulation with the carpal bones. Instead, the triquetrum articulates with a fibrocartilaginous pad that spans the radius and the styloid process of the ulna, allowing the ulna to contribute to the wrist joint indirectly. This intricately structured joint allows for the range of motions necessary for hand and wrist movements.
