y. saphena parra (see also 

 Fig. 506) l)egins behind the lateral 

 malleolus as the continuation of the 

 V. niarginalis lateralis of the ioot; in 

 its furination there take part, besides 

 superficial branches of the rete venosuni 

 plantare cutaneiim, also an anastomosis 

 from the deep vv. plantares laterales. 

 It runs at first on the lateral margin, 

 then on the posterior surface - of the 

 tendo calcaneus [Achillis] ; farther up 

 ensheathed in a duplicature of the fascia 

 cruris, it lies in the groove between 

 the two heads of the m. gastrocnemius, 

 perforates the fascia at a variable level, 

 sinks into the depth in the 2)ophteal 

 space and always bifurcates into two 

 branches, of which one opens into the 

 posterior wall of the v. poplitea and 

 the other farther up into the beghuiing 

 ]iortiiin of the v. profunda femoris. 

 The latter branch also receives a vessel 

 of superficial course, running on the 

 back of the thigh, the v. femoropoplitea, 

 the contents of which flow for the most 

 part from above downw^ard but can 

 also find a channel of exit by passing 

 upward beneath the m. glutaeus maxi- 

 mus into the vv. glutaeae. The v. sa- 

 phena parva receives in its course 

 numerous branches from the superficial 

 network of the heel and of the leg 

 and anastomoses usually manifoldly 

 with the V. saphena magna. It may 

 open also into other deep veins of the 

 thigh or into the v. saphena magna.
