Posterior Interosseous Artery: Key Forearm Blood Supplier
The posterior interosseous artery, a vital blood vessel in the forearm, has been studied extensively, notably by anatomist Friedrich August von Ammon. It plays a crucial role in supplying oxygenated blood to the forearm's muscles and veins.
The artery, also known as the interosseous artery, runs the entire length of the forearm. It lies beside the interosseous membrane and the oblique cord, nestled between the radius and ulna bones. Alongside the dorsal interosseous artery, it courses through the forearm.
At the bottom of the forearm, the posterior interosseous artery meets the volar interosseous artery, joining forces to create part of the dorsal carpal network. This network ensures blood supply to the hand and wrist. The artery's journey begins with a connection to the radial collateral branch of the profunda brachii.
The posterior interosseous artery's strategic location and course make it a vital component of the forearm's circulatory system. Its connection to the radial collateral branch of the profunda brachii and its role in forming the dorsal carpal network highlight its importance in maintaining blood flow to the forearm, hand, and wrist.
