What is the radius bone in the arm?
The radius is the thicker and shorter of the two long bones in the forearm. It is located on the lateral side of the forearm parallel to the ulna (in anatomical position with arms hanging at the sides of the body, palms facing forward) between the thumb and the elbow.
What bone is the radius?
forearm
The radius is one of the two bones that make up the forearm, the other being the ulna. It forms the radio-carpel joint at the wrist and the radio-ulnar joint at the elbow. It is in the lateral forearm when in the anatomical position. It is the smaller of the two bones.
What bones does the radius touch?
The radius is located on the lateral side of the forearm between the elbow and the wrist joints. It forms the elbow joint on its proximal end with the humerus of the upper arm and the ulna of the forearm.

What bone is located on the medial side of the forearm?
The ulna
The ulna is located on the medial side of the forearm, and the radius is on the lateral side. These bones are attached to each other by an interosseous membrane. More distal is the shaft of the ulna. The lateral side of the shaft forms a ridge called the interosseous border of the ulna.
Which bone is bigger radius or ulna?
Now let’s look at the two forearm bones, the radius and the ulna. They’re different, in that the ulna is bigger proximally, the radius is bigger distally. The main feature of the proximal end of the ulna is this large curved articular surface. The curve that it forms is called the trochlear notch.

What does it mean when your radius hurts?
