Corpus: Common interosseous artery

The common interosseous artery is a short, approximately 1 cm long branch of the ulnar artery.

The common interosseous artery originates directly below the radial tuberosity. It runs dorsally to the upper edge of the interosseous antebrachial membrane, where it divides into 2 branches:

• Anterior interosseous artery
• posterior interosseous artery

As a variation, the recurrent interosseous artery can also originate directly from the common interosseous artery instead of the posterior interosseous artery.
