Origin
The radialis indicis artery may originate from the princeps pollicis artery; however, it may also arise from the superficial palmar arch or the first dorsal metacarpal artery (Standring, 2016).
Course
The radialis indicis artery courses distally between the first dorsal interosseous and the transverse head of the adductor pollicis muscles. It continues on the lateral aspect of the second digit, or the index finger, to the distal phalanx. It anastomoses with the princeps pollicis artery and the superficial palmar arch at the inferior margin of the transverse head of adductor pollicis muscle (Standring, 2016).
Branches
There are no named branches.
Supplied Structures
The radialis indicis artery contributes to the supply of the lateral aspect of the index finger.

Artery
When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
