Wrist bone

The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term 'carpus' is derived from the Latin carpus and the Greek καρπός (karpós), meaning 'wrist'. In human anatomy, the main role of the wrist is to facilitate effective positioning of the hand and powerful use of the extensors and flexors of the forearm, and the mobility of individual carpal bones increase the freedom of movements at the wrist.Position of carpal bones (shown in red).

The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term 'carpus' is derived from the Latin carpus and the Greek καρπός (karpós), meaning 'wrist'. In human anatomy, the main role of the wrist is to facilitate effective positioning of the hand and powerful use of the extensors and flexors of the forearm, and the mobility of individual carpal bones increase the freedom of movements at the wrist. In tetrapods, the carpus is the sole cluster of bones in the wrist between the radius and ulna and the metacarpus. The bones of the carpus do not belong to individual fingers (or toes in quadrupeds), whereas those of the metacarpus do. The corresponding part of the foot is the tarsus. The carpal bones allow the wrist to move and rotate vertically.
