Lymphatic Glands. These are usually divided into two sets, the inguinal, placed 

 along the line of Poupart's ligament, and the femoral, placed along the saphenous vein. 

 The femoral glands receive the lymph from the dorsum of the foot, the inner side, and 

 front of the legs and thigh. The inguinal may be subdivided into three groups, an inner, 

 which receives the lymph from the skin of penis, scrotum or labia, anus, and ischio- 

 rectal fossa ; a middle, which receives the lymph from the lower part of the front of 

 the abdomen; and an external, which receives the lymph from the buttock and 

 flank. 



The femoral sheath is a funnel-shaped structure, which is derived from the trans- 

 versalis fascia in front and the iliac fascia behind as the artery passes under Poupart's 

 ligament ; it is divided into three compartments by means of fibrous septa, an outer one 

 for the femoral artery, a middle for the femoral vein, and an inner one, which is very 

 short, containing the lymphatics which pass from the glands in the groin to the deep 

 inguinal lymphatic glands. It is called the crural canal, and through it a femoral 

 hernia passes when present. This canal is bounded above by Poupart's ligament ; below by 

 the peetineus musclo covered by the pectineal portion of the fascia lata, and the ramus 

 of the pubes ; internally by Gimbernat's ligament; and externally by the middle com- 

 partment of the femoral sheath containing the femoral vein. A hernia passing down 

 the canal is thus covered by (1) peritoneum ; (2) septum crurale, which is continuous 

 with the subperitoneal tissue ; (3) fascia transversalis ; (4) cribriform fascia ; (5) super- 

 ficial fascia and skin.
