DISSECTION OF THE DOG 87 



Veins of the dorsum oe the pes.— On the dorsal aspect of each digit 

 two veins are to be distinguished, the dorsal digital veins (vv. digitales 

 dorsales). These join to form three or four common dorsal digital veins 

 (vv. digitales communes) which, in their turn, form the radicles of one large 

 dorsal m.etatarsal vein (v. metatarsese dorsahs). This smgle vein crosses the

 then passes obHquely over the lateral face of the leg and disappears medial 

 to the biceps muscle to become the small saphenous vein (vena saphena parva), 

 which finally ends in either the femoral or the popliteal vein. 



The medial side of the metatarsus and tarsus is drained into the large 

 saphenous vein (vena saphena magna).
