The ulna does not directly articulate with any carpal bones. Instead, it forms a joint with the triangular fibrocartilage complex (TFCC) located at the wrist, which interfaces with the carpal bones, particularly the lunate and the triquetrum. The radius, however, articulates with the scaphoid and lunate carpal bones.
The carpals articulate distally with the ulna. The carpals are also known as the wrist bones.
The bone in the forearm that articulates with the carpels at the wrist joint is the radius. The other forearm bone (the ulna) doesn't articulate withe the carpals because a cartilaginous disc sits between the carpals and the ulna.
The radius and ulna are proximal to the carpal bones. The carpals are distal to the radius and ulna.
Moves the ulna
The ulna is proximal to the carpal bones. The carpal bones are distal to the ulna.
At the distal end: the carpels in the hand at the head of the ulna and the radius at the ulna notch of radius. At the proximal end: the trochlea of the humerus at the trochlear notch and coronoid process of the ulna and the head of the radius at the radial notch of the ulna.
Radial and ulnar styloids.
The metacarpals articulate proximally with the carpals. In particular, the first metacarpal articulates with the trapezium. The second articulates with the trapezium, trapezoid, and capitate. The third articulates with the capitate. The fourth articulates with the capitate and hamate. The fifth metacarpal articulates with the hamate.
