Etymology: L, elbow
the bone on the medial or little finger side of the forearm, lying parallel with the radius. Its proximal end bulges into the olecranon and the coronoid processes and dips into the trochlear and radial notches. The ulna articulates with the humerus and the radius. Also called elbow bone.

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.

ulna
