THE VESSELS. 349 



b. Lymphatics: 



1. The deep accompany the deep-seated blood-vessels on the anterior and 

 posterior surface of the inferior extremity. The anterior pass into the 

 gl. tibial. antica, the posterior into the gl. poplitcea, and thence along 

 the v. cruralis into the gl. inguinal, prof. 



2. The superficial arise in the skin of the foot, the posterior partly from 

 the sole, corresponding with v. saphena parva; the anterior come off 

 from the back of the toes, incline inwards, ascend on the inner side of 

 the leg, then upon Sartorius to the superficial inguinal glands, accom- 

 panying the V. saphena magna. 



2. The surface of the external parts of generation. The superficial lym- 

 phatics of the scrotum and penis (or the inferior portion of labia majora), be- 

 take themselves to the deep and most superior inguinal glands, also those of 

 the rectum; they correspond to the vasa pudenda externa. 



3. Anterior inferior abdominal walls, the loins and buttocks. Their super- 

 ficial lymphatics, as well as some which accompany vv. epigastric, and cir- 

 cumflex, ilei, pass to the superficial and superior inguinal glands. 



4. Internal surface of the pelvic and abdominal walls : 



a. Lymphatic glands : 



1. Gl. iliaccB externcB (six to eight), along the vasa iliaca externa and 

 commun. upwards to the fifth lumbar vertebra ; three thereof are placed 

 close behind the femoral ring on the outer, the inner, and anterior sur- 

 face of the femoral vessels. 



2. Gl. hypogastriccs (nine to twelve), upon and close to vasa hypogastrica, 

 are traversed by the lymphatics from the interior of the organs of t ge- 

 neration (vas. pudenda internal. 



3. Gl. sacrales (four to five), laterally before the promontorium in the me- 

 sorectum. 



4. Gl. lumbales s. aorticce (twenty to twenty-five), on the sides of the 

 aorta (especially this) and vena cava, upwards. 



b. Lymphatics : 



1. Plexus iliacus externus. The lymphatics pass out of the inguinal 

 glands, through fascia cribriformis, behind the v. cruralis into the 

 pelvis, under the peritonaeum to the gl. iliacce, forming a plexus about 

 the artery; on the other side to the gl. hypogastricce, where they form 



2. Plexus hypogastricus, about art. hypogastrica, and also 



3. Plexus sacralis on the posterior pelvic wall, passing into the 



4. Plexus lumbalis (and gl. lumbalis). This plexus extends around the 

 aorta abdominal, and v. cava inferior, receives the lymphatics of the 

 kidneys, testicles, and spermatic cords, and the female internal organs 

 of generation, and forms the lateral roots of the ductus thoracicus. 



5. Of the urinary organs : 



1. Lymphatics of the kidneys and supra-renal capsules, are superficial 

 and deep. The last pass forth at the hilus of the kidney, form plexuses,
