Where does the radial artery terminate?

The radial artery is a major artery in the forearm that plays a crucial role in supplying blood to the hand. It originates from the brachial artery and travels down the forearm, eventually terminating in the deep palmar arch. The deep palmar arch is formed by the anastomosis of the radial artery and branches from the ulnar artery, and it is responsible for supplying blood to the deep structures of the hand, including the metacarpal and digital arteries.

Understanding the anatomy and function of the radial artery is essential for those studying vascular ultrasound, as it helps in identifying the importance of this vessel in clinical assessments and interventions. The deep palmar arch ensures that the hand receives an adequate blood supply, which is critical for its mobility and functionality.
