 connection with the vessels of the metatarsus. 



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

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

 tarsal bone underneath the extensor dip^itorum brevis and the tendon 

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

 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.
