The ulnar artery lies lateral to the pisiform bone [probe]. Follow the ulnar artery into the palm of the hand, where it is the major artery that forms the superficial palmar arterial arch (Figure 8.2). The superficial branch of the radial artery usually joins the branch of the ulnar artery to complete the superficial palmar arch.
Clean the superficial palmar arch and identify the common palmar digital arteries [superficial to the pipe cleaner on the left] which arise from it and give the proper palmar digital arteries to the fingers.
