wrist

 [rist]
the region of the joint between the hand and the forearm; it contains eight bones, called the carpal bones (see anatomic Table of Bones in the Appendices). The bones are arranged in two rows, whose joint surfaces glide upon each other in four directions; they join the bones of the forearm, the radius and ulna, as well as the bones of the hand, the metacarpals. They are bound together and protected by tough ligaments and capsules, the enveloping structures. The major arteries, nerves, veins, and tendons that serve the hand and fingers run across the wrist. Both the tendons and the joint are lined with synovial membrane. Called also carpus.

wrist

The complex, many-boned joint between the hand and the arm. The eight wrist bones, or carpals, are arranged in two rows, the nearer row, which articulates with the forearm bones, containing the scaphoid, lunate, triquetral, and pisiform bones, and the farther row the trapezium, trapezoid, capitate, and hamate. These are connected to the bones of the palm, the metacarpals. Many tendons, connecting forearm muscles to the fingers and thumb, run through the wrist. These pass under ligamentous straps (retinacula) which prevents them from springing away from the wrist. Arteries and nerves also pass through the wrist.
