The proper palmar digital arteries (or volar) travel along the sides of the phalanges, just posterior to the corresponding digital nerve.
The proper palmar digital artery for the medial side of the little finger arises directly from the ulnar artery deep to the palmaris brevis muscle, but the rest arise from the common palmar digital arteries.
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.
