What is the name of the articulations that connect the wrist bones to the bones of the palm?

• A. Metacarpophalangeal joints
• B. Carpometacarpal joints
• C. Interphalangeal joints
• D. Distal radioulnar joints

Answer: (B)

The articulations that connect the wrist bones to the bones of the palm are known as the carpometacarpal joints. These joints are crucial because they facilitate the movement and function of the wrist and hand by allowing for a range of motions between the carpal bones in the wrist and the metacarpal bones of the palm. Each carpometacarpal joint is formed between a carpal bone and a metacarpal bone, providing flexibility and stability during hand activities.

Other options do not refer to the connections between the wrist and the palm. For instance, metacarpophalangeal joints connect the metacarpal bones to the proximal phalanges of the fingers, while interphalangeal joints are the hinge joints between the individual phalanges. The distal radioulnar joints involve the radius and ulna, facilitating forearm rotation rather than connecting the wrist to the palm.
