(The li;^-. inguinale and the nnu. sarturiu.s, rectus femoris, pectineus and adductor longus have 

 l^een entirely or partially removed; a piece has been cut out of the^a. femoralis.) J 



T. femoralis (continued): 



5. V. saphena magna (see p. 471). 



6. y. profunda femoris accompanies the a. prnfunda femoris and possesses several 

 pairs of valves. Branches: 



a) ViK per'forantes (sec also Fig. 506), ])artly doubled, arise du tln^ posterior surface of 



the m. adductor magnus and comnmnicate freely there by longitudinal anastomoses with 

 one another, with the vv. glutaea inferior, circumflexa femoris medialis and with 

 the V. poplitea; they then perforate the mm. adductores near the aa. perforantes. 



b) Vv. circumflexue femoris mediales (see also Fig. 506) run near the corresponding 



arteries and anastomose freely lichind, on the m. quadratus femoris, with the vv. glutaea 

 inierior and perforans I, in front with the v, ol)turatoria. They are supplied with valves. 



c) Vv. circwnflexae femoris later ales, supplied with valves, accompany the a. circumflexa 



ienioris lateralis and anastomose with the ])receding and with the v. glutaea inferior. 

 y. poplitea (popliteal vein) (see Fig. 506) arises froui the union of the vv. tiliiales 

 and runs just behind the a. poplitea, in its distal part at the same time somewhat medianward, 

 in its proxiiual part somewhat lateralward from it. Besides, near the artery there is below a 

 V. comtians lateralis, above a v. comituns medialis. It is su])plied with valves, receives the 

 v. saphena parva (see p. 472) and the vv. articulares genu (double near the corresponding 

 arteries, not illustrated) and anastomoses with the lower \v. perf irantes.
