The wrist joint includes the following structures: the radius bone, the ulna and the carpal bones. The radius bone is located close to the thumb, while the ulna is close to the little finger. Carpal bones include eight parts - the proximal or distal bones.
The wrist has two important ligaments: the medial (ulnar) and lateral (radial) collateral ligaments. These ligaments connect wrist bones. Wrist muscles are mostly located in the forearm. Wrist muscles and tendons can help to stabilize wrist's movement.
The major wrist nerves include: the radial nerve, the median nerve, the ulnar nerve. These nerves help to transmit various signals.
