 beneath. 



The space between the crural arch and the hip-bone is larger in 

 the female than in the male, and is closed by parts passing from 

 the abdomen to the thigh. The outer half of the interval is filled 

 by the psoas and iliacus muscles, between which is the anterior 

 crural nerve, while the external cutaneous nerve lies on the iliacus 

 near the anterior superior iliac spine : in this part Poupart's liga- 

 ment is closely bound down to the muscle by its attachment to the 

 iliac fascia. The inner half is occupied by the femoral vessels and

 crural branch of the genito- crural nerve issues on the outer side of 

 the artery. 



Gimbernat's Gimbernafs ligament, or the piece of the tendon of the external 

 oblique muscle which is inserted into the pectineal line, is about 

 three-fourths of an inch in length, and is triangular in shape (fig. 97). 

 Its apex is at the pubic spine : while its base is in contact with the 

 crural sheath, and is joined by the falciform ligament of the fascia 

 lata. By one margin (anterior) it is continuous with the crural
