Fig. 1. FPMA arises from the deep branch of radial artery after it pierces the first dorsal interosseous muscle to continue as deep palmar arch. In this figure the first dorsal interosseous muscle is incised to show the course of FPMA running between the first dorsal interosseous and adductor pollicis muscles. APL, abductor pollicis longus; EPB, extensor pollicis brevis; EPL, extensor pollicis longus; FPMA, first palmar metacarpal artery; RA, radial artery.
