Anterior Interosseous Artery

Saturday, April 12, 2014

The anterior or volar interosseous artery is a blood vessel that arises from the common interosseous in the cubital fossa (upper part of forearm). Then, it runs down along the length of the forearm, between the ulna and radius, on the interosseous membrane. When it gets to the pronator quadratus muscle at the wrist, it turns backwards and anastomoses with the dorsal interosseous artery. The palmar branch of the median nerve travels parallel to this blood vessel. Function: it supplies the muscles and bones of the forearm with oxygen-rich blood.
