54 DISSECTION OF THE VASCULAR SYSTEM. 
correspond to the external pudic, being distributed to 
the external genital organs. This arrangement is dif- 
ferent from that in man. 
The second chief division of the internal iliac, the 
sciatic, after giving off two large branches, the »Zuteals, 
which supply the muscles on the back of the pelvis, 
passes along with the sciatic nerve through the sacro- 
sciatic foramen to reach the exterior of the pelvis, 
where it is distributed chiefly to muscles. 
12. The External Iliacs pass beneath Poupart’s liga- 
ment to reach the front of the thigh, where they are 
known as the femoral arteries. Before leaving the 
abdomen each gives off a large branch, which seems 
to have no homologue in human anatomy. This 
branch in turn gives off one or two branches, the 
eproastric artery, Which is distributed to the muscles 
of the anterior abdominal wall, and then passes be- 
neath Poupart’s hgament to reach the inner portion 
of the thigh, where it is distributed chiefly to the large 
adductor muscles. 
13. The Femoral Artery runs for some distance just 
below the sartorius muscle, giving off several 
branches to the muscles, and one long branch, the 
saphenous artery, which passes to the leg, lying 
below the skin. The femoral next bends sharply 
inward to reach the back of the knee-joint, where it is 
named the jopliteal artery, this divides into two 
branches, one rather large which passes into the leg 
between the tibia and fibula, and finally reaches the 
front of the leg. It corresponds to the azterzor tebcal 
of human anatomy, and may be followed down upon 
the dorsum of the foot. The second, smaller division 
sends branches to the lower portions of the muscles
