 of the tensor fasciae latse and glutseus maximus. This part of 

 the fascia lata is known as the ilio-tibial tract.

A large gap,, termed the fossa ovalis (saphenous opening), 

 occurs in the deep fascia just distal to the medial end of the 

 inguinal ligament. The centre of the opening lies i| inches 

 distal and lateral to the pubic tubercle (Stiles). It is traversed 

 by the great saphenous vein and is partially closed by the fascia 

 cribrosa. The lateral border of the fossa ovalis is sharp and 

 well denned. It is falciform in outline, and its superior cornu
