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:〔(Physiology of adult Homo sapiens - Systemic blood and lymph circulation (angiology) )〕 proper volar digital arteries,〔''Palmar'' and ''volar'' may be used synonymously, but ''volar'' is less common.〕 collateral digital arteries,〔Thus called because they run alongside (collateral to) the finger bones.〕 arteriae digitales palmares propriae,〔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.〕 or aa. digitales volares propriae.〔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.〕 They anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints. 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. ==See also== * Superficial palmar arch * Proper palmar digital nerves of median nerve 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Proper palmar digital arteries」の詳細全文を読む スポンサード リンク
