|Proper palmar digital arteries|

|Source||common palmar digital arteries|
|Vein||palmar digital veins|
|Latin||Arteriae digitales palmares propriae,
arteriae digitales volares propriae
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.
Each also 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 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.

- 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.
