carpus
Eight wrist bones
The carpus is the cluster of small bones forming the wrist—the joint connecting the forearm to the hand.
In humans, eight carpal bones arranged in two rows allow the wrist's complex movements.
The term appears mainly in anatomical and medical contexts: a fracture of the carpus, carpal tunnel syndrome.
