The radiocarpal joint is a synovial joint thatâs also found in the wrist. The radius articulates with the first row of carpal bones, except for the pisiform. It has a fibrous joint capsule thatâs attached to that distal end of the radius and the ulna and to the carpal bones.
There are 27 bones in the hand â eight in the wrist, called the carpals; five in the palm of the hand, called the metacarpals; and 14 bones in the fingers, called the proximal, middle, and distal phalanges. The two bones of the forearm, the radius and ulna also make up part of the wrist joint.The ability to move our fingers with precision enables us to perform a wide variety of everyday tasks. This precise motion is made possible by the joints in the hand, which enable the fingers to bend.he two bones of the forearm, the radius and ulna also make up part of the wrist joint.
