Corpus: Common interosseus artery

The common interosseous artery originates just below the tuberosity of the radius. It moves dorsally to the upper edge of the interosseous membrane of the forearm and divides there into two branches:

• Anterior interosseous artery

• Posterior interosseous artery

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