glands along its lower border. Deep. — Internal oblique along the outer 

 half, and transversalis abdominis along the outer third. Along the outer 

 half the fascia transversalis and fascia iliaca are attached, and form a 

 canal containing the deep circumflex iliac vessels. The fascia transversalis 

 continues to be attached to the inner part, but loosely and only as far inwards 

 as the base of Gimbernat's ligament. The deep crural arch is also a deep

relation. Poupart's ligament, along with the irregularly concave border of 

 the OS innominatum, forms a large fibro-osseous canal. This region is known 

 as the lacunar region. 



The deep femoral arch is a thickening of the fascia transversalis as it passes 

 downwards beneath Poupart's ligament to form the anterior wall of the 

 crural sheath. The thickening is due to superadded fibres which extend 

 inwards from the centre of Poupart's ligament on its deep aspect to the 

 ilio-pectineal line, where they are attached behind Gimbernat's ligament near 

 its base.
