Adductor longus, and the base, by Poupart's ligament. The floor of this space 

 is formed from without inwards by the Iliacus, Psoas, Pectineus, Adductor 

 longus, and a small part of the Adductor brevis muscles; and it is divided 

 into two nearly equal parts by the femoral vessels, which extend from the middle 

 of its base to its apex ; the

situation its cutaneous and 

 profunda branches, the vein 

 receiving the deep femoral 

 and internal saphenous 

 veins. In this space, the 

 femoral artery rests on the 

 inner margin of the Psoas 

 muscle, which separates it 

 from the capsular ligament 

 of the hip-joint. The artery 

 in this situation is crossed 

 in front by the crural 

 branch of the genito-crural 

 nerve, and behind by the 

 branch to the Pectineus 

 from the anterior crural. 

 The femoral vein lies at 

 its inner side, between the 

 margins of the Pectineus 

 and Psoas muscles. The 

 anterior crural - nerve lies 

 about half an inch to the 

 outer side of the femoral 

 artery, deeply imbedded 

 between the Iliacus and 

 Psoas muscles; and on the 

 Iliacus muscle, internal to 

 the anterior superior spi- 

 nous process of the ilium, 

 is the external cutaneous 

 nerve. The femoral artery 

 and vein are inclosed in a 

 strong fibrous sheath, form- 

 ed by fibrous and cellular 

 tissue, and by a process of 

 fascia sent inwards from 

 the fascia lata ; the vessels 

 are separated, however, 

 from one another by thin 

 fibrous partitions. 



In the middle third of the 

 thigh, the femoral artery is 

 more deeply seated, being 

 covered by the integument, 

 the superficial and deep 



fasciae, and the Sartorius, and is contained in an aponeurotic canal, formed by a 

 dense fibrous band, which extends transversely from the Vastus internus to the 

 tendons of the Adductor longus and Adductor magnus muscles. In this part of 

 its course it lies in a depression, bounded externally by the Vastus internus, 

 internally by the Adductor longus and Adductor inagnus. The femoral vein lies
