ulna

One of the pair of forearm long bones. The ulna is on the little finger side. At its upper end it has a hook-like process, the olecranon, that fits into a hollow at the back of the lower end of the upper arm bone (the humerus) and prevents the elbow from over-extending. When the hand is turned on the long axis of the arm, the radius bone rotates around the ulna.
