CIRCULATORY SYSTEM OF THE DOG 
which supply the ovary and uterine tube 
and anterior part of the cornu of the 
uterus, anastomosing with the uterine 
artery. 
The posterior mesenteric artery is 
small. It divides into two branches which 
supply the terminal part of the colon and 
the anterior part of the rectum; the 
former (A. colica sinistra) passes forward 
along the left part of the colon and anas- 
tomoses with the middle colic branch of 
the anterior mesenteric artery; the latter 
(A. hemorrhoidalis cranialis) anastomoses 
with the middle hemorrhoidal branch of 
the internal pudic artery. 
The circumflex iliac artery usually 
arises from the terminal part of the 
aorta. 
The external iliac artery usually gives 
off no collateral branches. 
The femoral artery has the usual 
course in the femoral triangle and canal. 
The deep femoral artery gives off the 
posterior abdominal and external pudic 
arteries by a very short common trunk 
In the female the external 
pudie divides into anterior and posterior 
branches; the former runs forward, sup- 
plies branches to the superficial inguinal 
lvmph glands, the mammary glands and 
skin, and anastomoses with the mammary 
branch of the internal thoracic artery; the 
posterior branch pursues a flexuous course 
between the thighs to the vulva, where its 
terminal branches anastomose with the 
internal pudic artery. In the male the 
artery crosses the medial side of the sper- 
matic cord and runs forward to the 
umbilical region; it supplies the inguinal 
lymph glands, prepuce, and skin. The 
anterior femoral artery may arise by a 
short common trunk with the lateral cir- 
cumflex. The former, accompanied by 
the anterior branch of the femoral nerve, 
dips in between the rectus femoris and 
vastus medialis. The lateral circumflex 
artery passes forward between the sar- 
torius medially and the rectus femoris 
and tensor fascize late laterally and sup- 
plies branches to these muscles and the 
glutei. In addition to muscular branches 
of considerable size, an articular branch 
(A. genu suprema) arises a little below 
the middle of the thigh and runs down-
