The proper palmar digital arteries travel along the sides of the phalanges (along the contiguous sides of the index, middle, ring, and little fingers), each artery lying just below (dorsal to) its corresponding digital nerve.
Alternative names for these arteries are:[1] proper volar digital arteries,[a] collateral digital arteries,[b] arteriae digitales palmares propriae,[c] or aa. digitales volares propriae.[d]
Proper palmar digital arteries anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints. Dorsal branches supplied by the arteries 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 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.

Notes and references
- ^ Palmar and volar may be used synonymously, but volar is less common.
- ^ Thus called because they run alongside (collateral to) the finger bones.
- ^ This is the official and international Latin term as defined by the Terminologia Anatomica (TA), but in English speaking countries and especially the US, proper palmar digital arteries is more commonly used.
- ^ Again, palmar and volar may be used synonymously, but aa. digitales volares propriae does not occur in the TA, and can therefore be considered deprecated.
