What is the anatomy of the wrist?
The wrist anatomy includes all the structures that make up the wrist joint itself. These are bones, ligaments, joint capsules and cartilage and muscles and other tissues around the joint. Known as a radiocarpan joint, the articulation on the wrist is located, where the bones of the radius in the forearm meet with the carpus, which is a cluster of small bones at the base of the hand. Exceeding the radiocarpal joint are ligaments connecting these bones, as well as tendons of muscles that move joints and other soft tissues such as nerves and blood vessels. Often, the discussion of the wrist anatomy often includes the distal Radioulnar joint, the articulation between the radius and the ulna bone in the forearm, which is located immediately above the radiocarpal joint. It is located where the distant end of the radius, one of the two long bones in the forearm, meets the hands at the end of the carpal bone. Karpus clustered like small rocks at the base of the hand, consisting of eight irregularly shaped bones. Bones in the proximal series that are articulated with the distal radius are calledOvi scaphid, lunate and triquetral bones.
Between the cards and the radius, another key part of the wrist anatomy, the joint disk. Since the joint of radiocarpal is a condyloid joint, it has an oval disk that fills the joint capsules between the bones to push them away against each other during many movements that the wrist can perform, including flexion and extension and kidnapping, or bending their hand to the pink or fire side.
The wrist anatomy also includes several main bonds, the stripes of fibrous tissue hold together the bones of the hand, wrist and forearm. The bonds hold eight carpal bones together just behind the radiocarpal joint. It is a radial carpal ligament, pisoham ligament and dorsal, palmar and interosseous intercarpal ligaments. Karpus is connected to a radius along the inch of the wrist with a radial collateral ligament and on the front and back of the wrist with Palmar and dorsal radiocarpal ligaments. Similarly, the carpus is connected to the ulna bone in the forearm, which runs parallel to the radius, but is not part of the wrist, Ulnar's collateral ligaments on the painting side of the wrist, as well as the Palm's Ullocarpal ligament on the on -board side of the plot. The ulna and the radius are connected to the swivel joint just above the wrist called the distal radioul joint Volar or Palmar and the dorsal radioulnar ligaments.
In addition to several nerves and blood vessels passing wrists, the anatomy of the wrist is completed by the forearm muscles as they enter the hand. On the front or palm surface of the wrist there are tendons of muscles that bend, kidnap and add wrist, including the muscles Flexor Carpi radialis and Ulnaris and the muscles Flexor Digitorum. The muscle tendons passing through the back surface of the wrist are those that belong to the muscles of the rear forearm, muscles that extend the wrists like extensor carpi radialis and ulnaris and extensor digitorum.
