 glands. 



the inner ankle, run up the leg with 

 the internal saphenous vein, pass with it 

 behind the inner condyle of the femur, 

 and accompany it to the groin, where 

 they terminate in the group of super- 

 ficial inguinal lymphatic glands which 

 surround the saphenous opening. Some 

 of the efferent vessels from these glands 

 pierce the cribriform fascia and sheath 

 of the femoral vessels, and terminate in 

 a lymphatic gland contained in the 

 femoral canal, thus establishing a com- 

 munication between the lymphatics of 

 the lower extremity and those of the 

 trunk : others pierce the fascia lata and 

 join the deep inguinal glands. The ex- 

 ternal group arise from the outer side 

 of the foot, ascend in front of the leg, 

 and. just below the knee, cross the tibia 

 frm without inward, to join the lym- 

 phatics on the inner side of the thigh. 

 Others commence on the outer side of 

 the foot, pass behind the outer malleolus, 

 and accompany the external saphenous 

 vein along the back of the leg, where they 

 enter the popliteal glands. 



The deep lymphatic vessels of the 

 lower extremity are few in number and 

 accompany the deep blood-vessels. In 

 the leg they consist of three sets, the 

 anterior tibial. peroneal, and posterior 

 tibial. which accompany the correspond- 

 ing blood-vessels, two or three to each 

 artery : they ascend with the blood- 

 vessels and enter the lymphatic glands 

 in the popliteal space ; the efferent 



-els from these glands accompany 

 the femoral vein and join the deep 

 inguinal glands ; from these, the vessels 

 pass beneath Poupart's ligament and com- 

 municate with the chain of glands sur- 

 rounding the external iliac vessels. 



The deep lymphatic vessels of the 

 gluteal and ischiatic regions follow the 

 course of the blood-vessels, and join the 

 gluteal and ischiatic glands at the great 

 Bacro-sciatic foramen. 



LYMPHATICS OF THE PELVIS AND 

 ABDOMEN. 



The Lymphatic Glands in the Pelvis 

 are the external iliac, the internal iliac, 

 and the sacral. Those of the abdomen 

 are the lumbar glands.
