Alternative names for these arteries are:[1] common volar digital arteries,[2] ulnar metacarpal arteries, arteriae digitales palmares communes,[3] or aa. digitales volares communes.[4]

Each of these arteries receive the corresponding volar metacarpal artery and then divide into a pair of proper palmar digital arteries (q.v.).

  3. This is the official and international Latin term as defined by the Terminologia Anatomica (TA), but in English speaking countries and especially the US, common palmar digital arteries is more commonly used.
  4. Again, palmar and volar may be used synonymously, but aa. digitales volares communes does not occur in the TA, and can therefore be considered deprecated.
