Detailed explanation-1: -The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is usually slightly longer than the radius, but the radius is thicker.

Detailed explanation-2: -It is located in the medial forearm when the arm is in the anatomical position. It is the larger of the two forearm bones.

Detailed explanation-3: -That is, the ulna is on the same side of the forearm as the little finger. It runs parallel to the radius, the other long bone in the forearm. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore, the radius is considered to be the larger of the two.

Detailed explanation-4: -The radius is shorter than the ulna and has a small proximal end that articulates with the humerus, and a broad distal end that articulates with the carpal bones at the wrist.

Detailed explanation-5: -The ulna is the longer of the two bones in your forearm. It helps you move your arm, wrist and hand. Your ulna also supports lots of important muscles, tendons, ligaments and blood vessels.
