bones, reaches the back of the tarsus, where it will be examined in 

 connection with the vessels of the metatarsus. 



The lateral dorsal metatarsal artery (a. metatarsea dorsalis lateralis) 

 passes obliquely over the lateral aspect of the base of the third meta- 

 tarsal bone underneath the extensor digitorum brevis and the tendon 

 of the perona?us longus, and then travels along the groove formed by 



M. perona-us tertius.

the union of the third and fourth metatarsal bones. Near the distal 

 end of the latter it passes between the two bones to reach the plantar 

 aspect of the metatarsus, where it will be met with later under the 

 name of the common digital artery. 



V. tibialis anterior. — The anterior tibial vein is frequently double, 

 one vein lying on each side of the homonymous artery. Its main 

 radicle of origin is the deep medial plantar metatarsal vein, which 

 accompanies the perforating tarsal artery in its passage through the 

 tarsus. The anterior tibial and saphenous veins are connected by a 

 large communicating vessel.
