Arteries of the Leg. 



435 



476. Arteries of the right 



th igh, vie wed from in front, deep layer. 



(The mm. sartorius, tensor fasciae 

 latae, rectus femoris, pectineus, ad- 

 ductor longus and gracilis have heen 

 removed.) 



2. A. circiimflexa ilium pro- 

 funda (deep circumflex ihac artery) 

 (see also Figs. 463. 467 and 4(38) 

 arises behind or below the lig. in- 

 guinale, passes hxteralwai-d and up- 

 ward in the groove between the mm. 

 transversus abdominis and iliacus, 

 gives oft' small branches to the neigh- 

 boring muscles, as well as one larger 

 branch upward between the mm. 

 transversus and obliquus internus 

 abdomiais (see Fig. 450) and extends 

 backward along the crista iliaca ; it 

 anastomoses with the r. iUacus a. 

 iliohunbalis. 



A. femoral is (femoral artery) 

 (see also Fig. 47.5) follows a fairly 

 straight course, in the groove between 

 the mm. pectineus and adductores 

 on the one hand, the m. iliopsoas 

 and m. vastus medialis on the other, 

 downward and medianward and fin- 

 ally through the canalis adductorius 

 (0. T. Hunters canal). It lies upon 

 the deep layer of the fascia lata and 

 is covered, from the inferior angle of 

 the trigonum femorale on, by the 

 m. sartorius. Above, it lies lateral- 

 ward fi'om the V. femoralis, further 

 down, it lies in front of the same 

 (see also Fig. 505). Branches : 



1) A. epigastrica superflcialis 

 (superficial epigastric artery) (see 

 Fig. 475) arises just below the lig. 

 inguinale, perforates the margo falciformis 

 and runs upward as far as the region of 

 the navel; it gives off branches to tbe skin 

 and to the m. obliquus externus abdominis. 



2) A.'circumflexa ilium superflcialis 

 (superficial circumflex iliac artery) (see Fig. 

 475), fretpiently a branch of the preceding, 

 goes lateralward, usually superficially upon 

 the fascia lata, to the spina iliaca anterior 

 superior and supplies the skin and muscles. 



3) Aa. pudeudae exteriiae (0. T. super- 

 ficial and deep external pudic arteries) (see 

 Fig. 475), usually two in number, run me- 

 dianward, in front of and behind the v. femo- 

 ralis, to the anterior surface of the scrotum 

 and penis (aa. scrotales anteriores) or of 

 the labia majora (aa. labiales anteriores). 



4) Rami iuguinales (see Fig. 475) to 

 the lymph glands and muscles of the fossa 

 iliopectinea. 



5) Rami musculares (see Fig. 475) to 

 the neighboring muscles and skin.
