 of the right thigh,

The deep yeins of the 



foot and leg (not iUustrated) 

 accompany the arteries, usually 

 two to each artery, and are 

 plentifully supplied with val- 

 ves. Numerous anastomoses 

 with the supei-ficial veins in 

 the foot lead the blood fi-om 

 the depth to the surface, in 

 the leg (also in the thigh) from 

 the surface to the depth. 



In the sole of the foot 

 they begin as the vv. digitales 

 plantares and then form the 

 vv. metatarseae plan- 

 tares, which empty part- 

 ly through several rami 

 per for antes into the deep 

 and the superficial veins 

 of the back of the foot, 

 partly into the arcns 

 venosus plantaris pro- 

 fundus. From the latter 

 go off the vu. plan- 

 tares later ales , which 

 by union with the finer 

 vv. plantares medialcs 

 form the vv. tibiales 

 posteriores; in the leg 

 the latter receive the 

 vv. peronaeae. The vv. 

 plantares laterales also 

 send an anastomosis to 

 the V. saphena parva, 

 the w. plantares me- 

 diales to the v. saphena 



On the back of the 

 foot they are relatively 

 delicate; they begin as 

 the vv. metatarseae dor- 

 sales pedis and are con- 

 tinued into the tt. ti- 

 biales aiiteriores.
