part of the upper (anterior) pentadactyl extremity of vertebrates, located between the forearm and the metacarpus.

In man, the carpus consists of two rows of small bones connected by intercarpal joints. The first row is made up of the scaphoid, lunate, triquetrous, and pisiform bones, which (except the pisiform) are linked to the radius (radiocarpal joint). The second row, consisting of the larger and smaller multangular, capitate, and unciform bones, is linked to the metacarpal bones (carpometacarpal joint). The carpus increases the mobility of the hand.

In animals, the carpus is the base of the front paw and is located between the antibrachium and the metacarpus.
