FASCIjE 



467 



Beyond the inguinal ligament the fasciae of the ilio-psoas and pectineal muscles Une a 

 triangular space, the ilio-pectineal fossa,* through which run the femoral vessels (fig. 407). 

 The sartorius muscle partly overlies the distal lateral margin of this fossa. The fascia lata is 

 here reflected from the surface of the sartorius to the ilio-psoas fascia, and becomes fused with 

 it. From the medial margin of the sartorius a process of the fascia is continued over the lateral 

 and upper part of the fossa, and is attached to the inguinal and lacunar (Gimbernat's) liga-

ments (fig. 389). Over the lower extremity of the fossa a process is continued medially into 

 the pectineal fascia. On the medial margin of the fossa the fascia lata is continued directly 

 into the pectineal fascia. The lateral concave margin of the fascia overlying the fossa is called 

 the falciform margin; the upper extremity of this, the superior cornu; the distal extremity, the 

 inferior cornu. The oval space bounded by the margo falciformis is called the fossa ovalis 

 (saphenous opening). This is covered by the fascia cribrosa, which some consider a deep layer 



*This lies within Scarpa's triangle [trigonum femorale], a space bounded by the inguinal 

 (Poupart's) Ugament and the sartorius and long adductor muscles.
