No carpal bone articulate with the ulna. Ulna takes part in elbow joint and radius in wrist joint. The inter-osseous membrane between the two bones, plays very important role in transmission of the force across the fore arm. The best of the architect would not have imagined this type of transmission of the force.
The radius articulates with more of the carpal bones than 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.
A lateral carpal is one of the small bones located in the carpus, or wrist, of the horse. It is also known as the radial carpal bone. The lateral carpal bone articulates with the radius and the third carpal bone (carpometacarpus).
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.
The carpal bones are connected to the radius bone through the radiocarpal joint, which is a synovial joint that allows for movement of the wrist. The radius bone articulates with the scaphoid and lunate carpal bones at the wrist.
The radius articulates with more of the carpal bones than the ulna.
The ulna is a bone of the arm, and the tibia is a bone of the leg. They have no articulations.

The lower extremity of the radius actually has two bones which it articulates with. The carpal and the ulna.
The styloid process of the Ulna (one of the bones of the forearm) is where the Ulna connects to the ligament of the wrist joint. The Triquetrum, Lunate and Pisiform carpal bones all lie distal to this. However the carpal bone most easily palpable is the Pisiform bone.
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.
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.

The carpal bones are connected to the radius bone through the radiocarpal joint, which is a synovial joint that allows for movement of the wrist. The radius bone articulates with the scaphoid and lunate carpal bones at the wrist.
The ulna articulates with:the humerus at its proximal end (end closest to the elbow)the radius at its radial notch (near the top part of the ulna) and at the ulnar notch (near the bottom part of the ulna)the wrist (separated by a fibrocartilaginous disc) at its distal end (end closest to the hand)
The bone that runs along the thumb side of the forearm is called the radius. It is one of the two bones in the forearm, the other being the ulna. The radius is located on the same side as the thumb when the palm faces up.
