Which joint is specifically located at the wrist?

The carpal joint is specifically located at the wrist because it refers to the group of eight small bones that make up the wrist (or carpus) and the joints formed between these bones. The carpal bones articulate with both the radius and the ulna to support wrist movement and stability. This group is essential for the function of the wrist as it enables a wide range of motion, including flexion, extension, and rotational movements.

The other options, while related to the wrist area, do not specifically represent joints at the wrist. The ulnar and radial refer to bones in the forearm that play a role in wrist function but do not directly represent a joint themselves. The scaphoid, although a carpal bone within the wrist, is not a joint but rather one of the eight bones that comprise the carpal bones. Therefore, identifying the carpal joint accurately reflects its specific location at the wrist.
