arising just above Poupart's ligament and ascending in the 

 abdominal wall; and deep circumflex iliac, running outward 

 above Poupart's ligament and the iliac crest, in the abdominal 

 wall. [856] 



Femoral. Beginning at the lower border of Poupart's liga- 

 ment, midway between the pubic symphysis and anterior su- 

 perior iliac spine, this descends to the opening in the Adductor 

 magnus and there becomes the popliteal artery. Its course is a 

 line from its origin to the adductor tubercle, when the thigh is 

 flexed and rotated outward. Entering the base of Scarpa's 

 triangle in the outer compartment of the femoral sheath, it de- 

 scends to the apex, gradually getting in front of its vein, and 

 then descends throughout Hunter's canal, also in front of its 

 vein though somewhat internal below. [858] 



The superficial circumflex iliac arises near Poupart's liga- 

 ment, pierces the femoral sheath and fascia lata, and runs to the 

 anterior superior iliac spine. The superficial epigastric, arising 

 near the preceding, pierces the femoral sheath and cribriform 

 fascia and ascends on the abdominal wall between the layers of 

 superficial fascia. The superficial external pudic pierces the 

 femoral sheath and cribriform fascia and runs over the pubic 

 spine to the external genitals. The deep external pudic runs 

 inward on the Pectineus to the external genitals. Muscular 

 branches supply the thigh muscles. [859] 



The profunda arises from the outer side of the femoral, about 

 an inch and a half below Poupart's ligament; it descends be- 

 hind the femoral (separated by the Adductor longus) , close to 

 the femur, to the lower third of the thigh where it pierces the 

 Adductor magnus as the fourth perforating artery. Its 

 branches are as follows : External circumflex; running outward 

 under the Sartorius and Rectus and dividing into three ter- 

 minal branches, ascending, transverse, and descending. Inter- 

 nal circumflex; running straight backward to the upper border 

 of the Adductor magnus and dividing into two branches ; as- 

 cending, to the digital fossa of the femur; and transverse,
