Wrist. The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones. This arrangement of bones allows for a wide range of movement. The wrist can bend, straighten, move laterally, and rotate. It is relatively prone to injury.
Arteries are multi-layered tubes that take blood from the heart to other places in the body. There are six arteries that travel into the hand. They are: Named for its shape of an arch, the deep palmar arch is small but important. This vessel sends off small branches to supply blood to the thumb and index finger.
The radial artery travels across the front of the elbow, deep under muscle until it comes to the wrist. This artery comes close to the skin surface. You can feel the pulse of the radial artery on the thumb side of the wrist.
