THE LOWER EXTREMITY, ANTERIOR, 573 



crest of the ilium. In its course it gives off twigs to the 

 iliacus, sartorius muscles, and the inguinal lymphatic 

 glands. 



(3) The superficial (superior) external pudic arises 

 from the inner side of the femoral, passes through the fascia 

 lata or the saphenous opening, extends upward and inward 

 to the lower part of the abdomen, where it meets its fellow 

 from the other side. As it is opposite the side of the root 

 of the penis it gives off the superficial dorsal artery to 

 that organ. 



(4) The deep (inferior) external pudic. A branch in 

 common with the above, or just below it, from the inner 

 side of the femoral. It takes a course inward across the 

 pectineus and adductor longus muscles (to which it gives 

 muscular branches) passes through the fascia lata at the 

 inner border of the adductor longus, breaks up into 

 branches which supply the scrotum (labium in the female) 

 and the inner side of the thigh. 



(5) The deep femoral. See page 579. 



(6) The anastomotica magna. This artery is given off 

 from the femoral just before it turns backward through the 

 femoral opening, at the lower end of Hunter's canal. 



It divides into two branches, the superficial and deep. 

 The former takes a superficial course along with the long 

 or internal saphenous nerve to the inner side of the knee, 

 while the latter, the deep branch, takes a deeper course 

 through the fibres of the vastus internus muscle in front 

 of the tendon of the adductor magnus to the deeper parts 

 about the knee. Both of these arteries enter into an an- 

 astomosis with the internal articular branches from the 

 popliteal ; the superficial with the inferior, and the deep 

 with the superior, internal articular branches. 



(7) The muscular branches. These are small branches,
