[The end of the deep palmar arch on its ulnar face]

In 95.5% the radial artery unites in the depth of the palma manus with an artery, which finds its origin in the ulnar artery or one of her branches. In 20.9% this artery originates from the ulnar artery proximally to the Hamulus ossis hamati and joins the Ramus profundus nervi ulnaris to reach the depth of the palma manus. In 74.6% the artery originates distally to the Hamulus ossis hamati and passes the Hypothenar muscles on their radial side to reach the radial artery. This second, rarely mentioned, artery is the branch of the Arteria digitalis palmaris propria for the ulnar margin of the fifth finger, an Arteria digitalis palmaris communis or the Arteria ulnaris.
