GeoByte1:The ulna is the forearm bone that's on the same side as your pinky finger.
GeoByte2:The ulna is the smaller of the two bones in the forearm.
GeoByte3:The arm and leg are similar in structure. Each has a long sturdy upper bone, a hinged joint, and two lower bones side by side.
GeoByte4:The elbow is the point of the ulna. Hitting your elbow sharply often irritates the ulnar nerve. We call this "hitting your funny bone."
GeoByte5:When the ulna is broken, a doctor will set the bone so that it will grow together correctly. Bones that do not heal can be patched with bone from a bone bank.
