(The m. glutaeus maximus has been re- 

 flected inward, the mm. glutaeus medius, 

 (juadratus femoris and caput longum m. 

 bicipitis have been partially removed.) 



6) A. genu suprema (0. T. anasto- 

 motiea magna) (see Fig. 47G) goes off in 

 the canalis adductorius, perforates its an- 

 terior medial wall, runs downward between 

 it and the m. sartorius behind the epi- 

 condylus medialis and finally accompanies 

 the n. sai)henus for a variable distance 

 (ramus sapheiius). It gives off rami 

 ijiuscularis, as well as a ramus musculo- 

 uriicuLares (0. T. deep branch) in the 

 m. vastus medialis and rami articulares 

 (0. T. superficial branch) below the same 

 to the rete articulare genu. 



7) A. profiiuda femoris (0. T. pro- 

 funda or deep femoral arteiy) (see also 

 Figs. 475 and 476) arises in the fossa 

 iliopectinea and descends behind the a. 

 femoralis. It lies in front of the mm. 

 iliopsoas, pectineus and adductor brevis, 

 covered by the m. adductor longus, and 

 ends as the a. perforans tertia. Branches: 



a) A. circumflexa femoris medialis (0. T. 

 internal circumflex artery) goes off near 

 the origin and runs medianward behind 

 the a. and v. femoralis. Branches: 



aa) Ramus superficialis , in front of the 

 m. pectineus, medianward between the 

 mm. adductores longus and brevis. 



ab) Ramus profundus, a larger branch, 

 bends upward , passes backward be- 

 tween the mm. iliopsoas and pectineus 

 and, below the m. obturator externus, 

 to the anterior surface of the m. qua- 

 dratus femoris. It sends branches to 

 the hip joint and divides into a branch 

 ascending to the fossa troclianterica, 

 and a branch descendinj^^^hind the 

 adductor muscles; it^/Siipplies the 

 neighboring muscles imd skin. 



b) A. circumflexa femoris lateralis [O.T. 

 external circumflex artery) lateralward 

 in front of the m. iliacus. Branches : 



ba) Ramus ascendens , goes upward and 

 lateralward beneath the m. rectus 

 femoris to the mm. glutaei and tensor 

 fasciae latae and to the fossa tro- 

 chanterica. 



bb) Ramus descendens , a larger branch, 

 downward and lateralward beneath the 

 m. rectus femoris between the mm. vasti 

 intermedius and lateralis almost to the 



knee; it also gives off' branches to the skin. 

 c) A. perforans prima (0. T. superior or first 

 perforating artery) perforates the adductors 

 at tiie lower margin of the m. pectineus:
