50 DISSECTION OF THE CAT 



femoral is called the popliteal artery, and, contin- 

 uing, divides into the anterior and posterior tibial 

 arteries. The posterior tibial artery runs down 

 behind the tibia to the inner side of the os calcis, 

 where it divides into the internal and external 

 plantar arteries. The anterior tibial artery 

 passes along the anterior part of the leg, and be- 

 comes the dorsal artery of the foot. 



14. The Internal Iliac Arteries are two large lateral 

 branches into which the aorta divides soon after 

 giving off the external iliacs. Each internal iliac 

 gives off a small artery to the bladder, the superior 

 vesical, and then divides into two branches, the 

 pudic and sciatic arteries. The pudic divides 

 into the internal pudic, which is distributed 

 within the pelvis to the genital organs, and the ex- 

 ternal pudic, which supplies the external genital 

 organs. The sciatic, after giving off the gluteal, 

 which is distributed to the muscles on the back of 

 the pelvis, passes out through the great sciatic 

 notch, and goes to the muscles of the hip and 

 thigh. 



15. The Caudal Artery is the posterior continua- 

 tion of the aorta. It passes along beneath the 

 tail. 



Muscular Branches are given off at various points, 

 both from the aorta and from other arteries to ad- 

 jacent muscles.
