CHAPTER VIII 



VEINS, LYMPHATICS, ARTERIES, AND NERVES AND 

 THEIR RELATIONS, LEFT INFERIOR LIMB 



The procedure for dissecting the inferior limb is essentially 

 the same as that for the superior limb. It is a good plan to 

 study figures 28 and 29 before beginning dissection in order to 

 get the relations of the trunk veins and artery to the inferior 

 vena cava (postcava) and aorta. Do not open the abdominal 

 cavity until work is begun on Chapter XI, or X, as directed 

 by the instructor. 



Method: Cut through the skin from the mid-ventral incision 

 along the medial side of the thigh and leg to about the middle of 

 the tibia; then continue the incision around the leg so that the 

 skin is separated in the middle region in such a way that the 

 undisturbed skin envelops the distal half of the leg and foot like 

 a stocking. Without making additional incisions in the skin, 

 loosen the skin from the proximal half of the leg and thigh and 

 reflex this free flap dorsad. It probably will be desirable to 

 continue the median abdominal incision caudad, passing to the 

 left of genitalia and anus, to the I'oot of the tail. Prepare the 

 thigh for dissection by removing the superficial fat and fascia 

 from the medial side and inguinal region.

LIMB 



(Fig. 29) 



It is not necessary for the student to study the veins and 

 lymphatics distad to the proximal third of the crus at this time, 

 but, because the blood in the veins flows toward the heart, it is
