the three, is situated outside and behind the foregoing : it is bounded posteriorly 

 by the ilium, anteriorly by Poupart's ligament and the iliac fascia, and internally is 

 separated from the pectineal compartment by the ilio-pectineal intermuscular septum : 

 it transmits the ilio-psoas muscle with the anterior crural and external cutaneous 

 nerves. The pectineal compartment, lodging the upper end of the pectineus 

 muscle, is between the pectineal fascia (or pubic portion of the fascia lata) in front 

 and the superior ramus of the pubis behind. It extends only a short distance 

 upwards beyond Poupart's ligament, being closed above by the attachment of the 

 fascia to the superior border of the pubic ramus. 



At the upper part of the pectineal fascia, immediately in front of its bony attachment, 

 is a thickening formed mainly by bundles of transverse fibres, which are closely connected 

 internally with, and in part derived from, Gimbernat's ligament. This is the pubic ligament 

 of Astley Cooper, and is frequently spoken of as Cooper's ligament.
