The anterior interosseous artery is also known as the volar interosseous artery. It is an artery of the forearm. The term “volar” refers to the palm of the hand or sole of the foot. This indicates that the artery runs along the underside of the forearm, which is also the palm side of the forearm. It originates from the common interosseous artery, which branches off from the ulnar artery. It flows along the interosseous membrane, a fibrous tissue that connects the ulna and the radius. The volar interosseous branch of the median nerve runs beside it. The artery provides nutrients to two muscles: the flexor digitorum profundis and the flexor policis longus. These muscles flex the fingers and thumb, respectively. The artery passes through the interosseous membrane to connect with the dorsal interosseous artery. It continues to the back of wrist. At that point, it merges with the dorsal carpal network. This network includes branches from the radial and ulnar arteries.
