Median artery

Median Artery

The Median Artery (Pronunciation: ME-dee-an AR-ter-ee) is a blood vessel that is present during the fetal development stage in humans. It typically regresses and is replaced by the radial and ulnar arteries, but in some cases, it may persist into adulthood.

Etymology

The term "Median" is derived from the Latin word "medius" meaning "middle", and "Artery" is derived from the Greek word "ἀρτηρία" (artēría), which means "pipe, conduit, or artery". The Median Artery is so named because it is located in the middle of the forearm.

Anatomy

The Median Artery arises from the Brachial Artery and runs down the center of the forearm, between the Flexor Digitorum Superficialis and the Flexor Digitorum Profundus. It gives off several branches that supply blood to the structures in the forearm and hand.

Clinical Significance

In some individuals, the Median Artery persists into adulthood and can be a significant source of blood supply to the hand. This is known as a "Persistent Median Artery". It can be identified using ultrasound or during surgical procedures in the forearm or wrist. The presence of a Persistent Median Artery can have clinical implications in conditions such as Carpal Tunnel Syndrome and during surgical procedures involving the wrist or hand.
