Question: 1 / 400

What is the major blood vessel of the upper arm?

Brachial vein

Basilic artery

Subclavian artery

Brachial artery

The major blood vessel of the upper arm is the brachial artery. This artery is a continuation of the axillary artery and runs down the length of the upper arm, supplying blood to the muscles and tissues in this region. It is the main artery that carries oxygenated blood from the heart to the arm and hand.

As the brachial artery descends, it gives off several branches that supply the surrounding structures, including the radial and ulnar arteries at the elbow, which further supply the forearm and hand. Its importance is emphasized in clinical settings, particularly in procedures such as measuring blood pressure and in various medical emergencies where vascular access is needed.

Understanding the anatomy and function of the brachial artery is crucial for healthcare professionals, especially those working in anesthesia and surgery, as they often need to know the vascular supply for various procedures and interventions.
