BLOOD VESSELS OF THE LEG

     In tetrapods, the iliac vessels which serviced fins in fish continue to form the femoral, saphenous, popliteal, and tibial vessels.  There is no common iliac artery in tree shrews and other placentals (such as cats).  In long tailed animals, the common iliac artery exists in embryonic development but is later modified.  In primates it persists.  Tree shrew blood vessels are intermediate between primates and other mammals (Funke, 1998).  In higher primates, the suralis artery ends further proximally (Funke, 1998).
