What Are the 2 Bones in Your Forearm Called?

Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius).

What are the bones in the forearms?

Your forearm is made up of two bones: the radius and ulna. In most cases of adult forearm fractures, both bones are broken. Fractures of the forearm can occur near the wrist at the farthest (distal) end of the bone, in the middle of the forearm, or near the elbow at the top (proximal) end of the bone.

Do the two bones in your forearm cross?

The radius is the forearm bone of the hand. The ulna is the forearm bone of the elbow. The two bones are not just associated at the elbow and wrist joints, but cross attached by a flexible sheet - like the two posts of a canvas stretcher. ... The motion stops when the radius bone abuts the ulna as the bones cross over.
