The lemoral artery, n prolongation of the external iliac, which changes 



its name <>n leaving the anterior border of the pubis, at first lies h neath the 



eniral arch. IK side a cluster of lymphatic glands, in the space comprised

From this interstice it descends, accompanied by its satellite vein, which li< s

internns, nt the posterior border of the long adductor of the leg. It soon 



s that muscle, however, to traverse the ring formed by the two brunches 



of the great adductor of the thigh and the oblique concavity on the posterior 



of the femur, and reaches the superior extremity of the gastrocnemii, 



n which it is continued, and assumes the name of popliteal ari< rtj. 

 On its course the feinoi-.il artery distributes a certain number of collateral 

 branches to the adjacent parts. These are: the prepubic, deep muscular, 

 superficial muscular, the small Htuxciilar, and saphena arterii-n.

1. Prepubic Artery. (Fig. 275, 4.) 



This artery originates at the artificial line of demarcation which separates 

 xternal iliac from the femoral artery, at the superior extremity of the 

 latter. It therefore emerges from that vessel at the anterior border of 

 tin- pubis, and never alone, but always with the deep muscular branch, 

 by means of a common and generally very short trunk, which springs at 

 an acute angle from the inner side of the femoral artery. 



The prepubic artery traverses the crural ring, opposite which it u 

 it lies on tlic anterior i'ace of I'oupart's ligament, behind the neck of the 

 vaginal sheath, and after a very short course separates into two branches 

 the /-.-</( r/or abdominal and i .it> ,-iml j.mli,- arteries.

This leaves the external pndic, artery at an acute angle, enters the femoral 



ring by crossing the direction of the spermatic cord, places itself between the 



small oblique and transverse muscles of the abdomen, passes forward 



: the external border of the great ivctns muscle, and finally enters the 



substance of that muscle, where its terminal divisions anastomose with those 



of the anterior abdominal artery. The numerous collateral branches this 



. throws oft" on its track principally go to the reel us muscle, or the 



t parts composing the infrrior abdominal \\all, the skin included: the 



superior branches communicate with .the circiindlexa ilii. 



Tli. position this artery occupies at its origin, and with reference to tho 

 uUlomi.'ial ring, is worthy of remark; indicating, as it does, that in 

 emulated inguinal hernia division of tin- ring should bo made outwards, 

 'd wounding the vessel.
