Anterior Interosseous Artery

Anterior interosseous artery and its branches (shown in red).

The Anterior Interosseous Artery (AIA) is a branch of the Ulnar Artery that supplies blood to the deep structures of the forearm. It is a significant artery in the human anatomy and plays a crucial role in the vascular supply of the forearm.

Anatomy[edit | edit source]

The Anterior Interosseous Artery originates from the Ulnar Artery, just below the elbow joint. It travels down the forearm, running along the interosseous membrane between the radius and ulna bones. It gives off several branches that supply the deep muscles of the forearm, including the flexor digitorum profundus and flexor pollicis longus muscles.

Clinical Significance[edit | edit source]

The Anterior Interosseous Artery is of clinical importance due to its role in the vascular supply of the forearm. It can be involved in conditions such as Anterior Interosseous Syndrome, a condition characterized by weakness in the flexor muscles of the forearm. Knowledge of the anatomy of the Anterior Interosseous Artery is also crucial in surgical procedures involving the forearm.
