| Tuberosity of the ulna | |
| Latin: | tuberositas ulnae |
The tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body. It provides an insertion point to a tendon of the brachialis (the oblique cord of the brachialis is attached to the lateral border).
