Radial artery of index finger
|Radial artery of index finger|
Palm of left hand, showing position of skin creases and bones, and surface markings for the volar arches.
|Latin||arteria radialis indicis|
|Source||deep palmar arch|
It arises close to the princeps pollicis artery, and descends between the first dorsal interosseous muscle and the transverse head of the adductor pollicis, and runs along the lateral side of the index finger to its extremity, where it anastomoses with the proper digital artery, supplying the medial side of the finger.
The princeps pollicis and radialis indicis may arise from a common trunk termed the first palmar metacarpal artery.
