Wrist (Carpus)

The wrist is the part of the hand between the forearm and the hand. It consists of eight small bones arranged in two rows.

The proximal (closest to the forearm) row contains the following bones:

1. Scaphoid
2. Lunate
3. Triquetral bone
4. Pisiform bone

In the distal (closest to the hand) row there are:

1. Trapezium bone
2. Trapezoid bone
3. Capitate bone
4. Hamate bone

The bones of the proximal row articulate with the radius of the forearm, and the bones of the distal row articulate with the metacarpal bones of the hand.

This structure ensures mobility of the wrist and facilitates the transfer of movements from the forearm to the hand.

***The wrist*** is a complex anatomical complex that ranks first among the skeletal joints of the upper extremities. It is represented by twelve bones: eight carpal bones, five metacarpal bones and only two sesamoid bones. The first word "wrist" (English "carpus") is associated with the Latin root "capito", which translates as **"**head**", "**"carnum" - **"**flesh**, " **and **"caput" - "head cap".***

***The most important bone of the wrist is the **scaphoid.*** It plays a large role in supporting the hand. With its help, support is achieved, the function of resting the ulna on the body. With its tubercles of the scaphoid (lateral and medial), the bone articulates with the trabeculae of the ulna. It is the ulna and radius bones of the human forearm that are formed. Without it, the hand would not be able to perform mechanical actions in the elbow joint.*** *The palmar part is located in the **lunate bone.*** It secures the support of the beam. A large protrusion on the adjacent bones is the ***pisiform bone.*** Between the right and left lunate bones the interosseous palmar ligament of the forearm with the palmar groove of the wrist is formed of the same name. On the ventral side of the outer (or palmar) face the convex marginal surfaces of the second intercarpal feature of the wrist. ***The carpal bone also has lateral ridges.*** Those are located in pairs

The wrist is an anatomical region consisting of eight bones. Located between the hand and forearm. The wrist bone plays an important role in the movement of the hand. It controls the movement of the finger bones through interaction with skeletal muscles. Next, we will consider in detail the anatomy of the wrist bones.

The bones of the wrist lie in two rows: the proximal row consists of four bones: the scaphoid, lunate, triquetrum and pisiform, and the distal row consists of another bone: the trapezium, trapezium, clavculus and trapezium.

The location of the bones in the wrist plays an important role in many movements of the hand, such as extension, flexion, and rotation. For example, the moon bone is used for rotation. And the triquetral bone controls flexion. The pisiform bone is used to bring the fingers together or apart. The head of the bone controls extension. Hamate bone -
