The region of articulation between the forearm and hand.
A joint between the hand and forearm.
Joint between the forearm and the hand, formed of eight carpal bones; also called carpus.
The area where the hand joins the arm. The wrist is a complex arrangement of joints between eight wrist bones (carpals in two rows of four bones each), two bones in the lower arm (radius and ulna), and five bones in the palm (metacarpals).
The region where the hand joins the arm. The wrist is a complex arrangement of joints between eight wrist bones (carpals in two rows of four bones each), the two bones of the lower arm (radius and ulna), and the five bones in the palm (metacarpals). This structure gives the wrist flexibility to move in a variety of directions and ways. The tendons that control the actions of the fingers pass through the wrist from the muscles in the lower arm that control them. Also passing across the wrist are the arteries and nerves supplying the muscles, bones, and skin of the hand and fingers.
The joint situated between the arm above and the hand below. It contains eight small carpal bones, arranged in two rows of four. Those in the row nearest the forearm are from the outside inwards when looking at the palm of the hand the scaphoid, lunate, triquetrum, and pisiform. Those in the row nearest the hand are the trapezium, trapezoid, capitate and hamate. These latter articulate with the metacarpal bones in the hand and are closely bound to one another by short, strong ligaments; the wrist-joint is the union of the composite mass thus formed with the radius and ulna in the forearm. The wrist and the radius and ulna are united by strong outer and inner lateral ligaments, and by weaker ligaments before and behind, whilst the powerful tendons passing to the hand and fingers strengthen the wrist.
The joint or region between the hand and the forearm.
The joint connecting the hand to the arm enables the hand to flex forward and backward in relation to the arm, as well as to move from side to side.
The wrist is composed of eight bones, collectively referred to as the carpus, which are organized in two rows. One row interacts with the bones of the forearm, while the other connects to the palm bones. Tendons link the muscles of the forearm to the fingers and thumb, and arteries and nerves provide nourishment and sensation to the muscles, bones, and skin of the hand and fingers.
Injuries to the wrist can result in impaired hand mobility and potentially cause disability. A frequent injury among adults is a Colles’ fracture, where the lower portion of the radius bone breaks, causing the hand to be pushed backwards. In young children, a similar backward displacement can occur due to a fracture at the epiphysis, or the growing end, of the radius. Sprains can also impact the ligaments in the wrist joint, although most are not particularly serious.
