Wrist joint

The wrist joint is the connection between the forearm and the hand. The wrist joint is formed by the radius and carpal bones - the scaphoid, semilunar and triangular. Movement is possible in it: flexion and extension, adduction and abduction of the hand.

The capsule of the wrist joint with its upper edge is attached to the radius and triangular cartilage, lower - to the first row of carpal bones.

On the palmar surface of the wrist joint there are two synovial sheaths, through which the finger flexor tendons pass, arranged in four layers. Extensor tendons at the level of the wrist joint
are located in the synovial sheaths and are located on the dorsum of the wrist joint in two layers.

The blood supply to the palmar side of the wrist joint comes from the radial and ulnar arteries, each of which is accompanied by two veins. Dorsum of the wrist joint receives blood from the back of the branches of the radial artery. Joint is innervated by branches of the ulnar and median nerves. Lymph flow is deep lymphatic vessels in the axillary lymph nodes.
