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.
在95.5%的情况下，桡动脉在手掌深部与一条动脉汇合，该动脉起源于尺动脉或其分支之一。在20.9%的情况下，这条动脉起源于钩骨钩近端的尺动脉，并与尺神经深支相连，到达手掌深部。在74.6%的情况下，该动脉起源于钩骨钩远端，经小鱼际肌桡侧至桡动脉。这条很少被提及的第二条动脉是供应第五指尺侧缘的掌固有动脉、掌浅动脉或尺动脉的分支。
