Three common palmar digital arteries (common volar digital arteries) arise from the convexity of the arch and proceed downward on the second, third, and fourth Lumbricales.
Each receives the corresponding volar metacarpal artery and then divides into a pair of proper volar digital arteries (aa. digitales volares propriæ; collateral digital arteries) which run along the contiguous sides of the index, middle, ring, and little fingers, deep to the corresponding digital nerves; they anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints.
Each gives off a couple of dorsal branches which anastomose with the dorsal digital arteries, and supply the soft parts on the back of the second and third phalanges, including the matrix of the fingernail.
The proper volar digital artery for medial side of the little finger springs from the ulnar artery under cover of the Palmaris brevis.
