what artery is in your wrist
Doctors determine if the blood supply to the hands is good by performing the Allen test. In the Allen test, your doctor presses his or her thumb against the ulnar artery, which is located in the âpinkie fingerâ side of the wrist. Your doctor will then press his or her other thumb on the radial artery, which is located on the thumb side of the wrist.
1 Radial recurrent artery - arises just after the radial artery comes off the brachial artery.  Superficial palmar branch of the radial artery - arises from the radial artery, just where this vessel is about to wind around the lateral side of the wrist.
