Etymology: "Saphenae" is the plural of "saphena", a Latin anatomical term for the large superficial veins of the leg. The Latin came from a Greek adjective, "saphēs", meaning "clear" or "evident", so the name refers to veins that can be seen beneath the skin. Anatomists used the term to distinguish these conspicuous veins from the deep veins hidden within the muscles. The two main vessels, the great and small saphenous veins, are the ones most often used in bypass surgery and vein grafts, which is why the name still appears in modern surgical practice.
