Hand bones, artwork. The hand is made up of 27 bones. Each of the four fingers comprises three phalanges bones, and the thumb contains two. The bones of the palm are the five metacarpals, which link the fingers to the eight carpal bones of the wrist. The carpals join the hand to the long bones of the lower arm; the radius (thumb side) and the ulna. This arrangement allows a great degree of flexibility.
