Common interosseous artery

The artery interosseous artery ( " common interosseous artery ") is an artery of the forearm. In humans, it is a branch of the ulnar artery, with the domestic animals a departure from the brachial artery. It owes its name to its location in the Zwischenknochespalt ( antebrachial interosseous space ) or the syndesmotischen connection between the radius and ulna ( interosseous membrane ).

The artery interosseous artery divides the forearm into two main branches: the anterior and posterior interosseous artery, with the domestic animals as interosseous artery cranial or caudal called. Both interosseous arteries anastomose distal interosseous in spatium.

Anterior interosseous artery

The anterior interosseous artery interosseous artery or cranial ( " anterior interosseous artery " ) runs along the front of the interosseous membrane. It supplies the flexor muscles ( flexors ) on the forearm and dismisses branches of the dorsal rete carpi. In ruminants and horses, it is the stronger of the two main branches.

Posterior interosseous artery

The posterior interosseous artery interosseous artery or caudal ( " posterior interosseous artery " ) runs along the back of the interosseous membrane. It supplies the extensor muscles ( extensor ) forearm and empties into the vascular arcades ( the superficial palmar arch and deep palmar arch ) at the origin of the metacarpal arteries. With predators and pigs it is significantly stronger than the front.
