magnus. It then passes I'ound to the back of the leg and gives 

 branches to tl>e adductor magnus, quadratus femoris_, biceps, and 

 gluteus maximus : it also gives off the arteria comes nervi 

 ischiadici. 



The deep cirouTnJlex iliac artery runs up to the ilium. It 

 supplies the sartorius and ilio-psoas, and ends between the 

 internal obliqvie and tra,nsversalis abdominis. 



The 2^'>^ofunda femoris gives off the lateral circumflex and a 

 branch passing back under the rectus femoris to the gluteus 

 medius. It then passes through the middle head of the adductor 

 magnus, supplies the adductor longus and vasti, and ends in the 

 biceps. There is no series of perforating arteries as in Man. 



The lateral femoral circumflex artery gives off: — 1. an ascend- 

 ing branch to the glutei, rectus femoris, and hip joint : 2, a 

 transverse artery to the gluteus maximus, vastus externus, and 

 hip joint ; 3. a descending artery to the rectus femoris, vastus 

 externus, crureus, and hip joint. 



The popliteal artery gives off muscular twigs to the heads of 

 the gastrocnemius, an articular artery to the knee and a geni- 

 cular trunk, the latter dividing into three branches: — 1. a 

 lateral geniculate artery which gives a nutrient artery to the 

 femur, a branch to the back of the joint and one which passes 

 round to the front of the capsule ; 2. a mesial genicular artery 

 which supplies the capsule in the popliteal space ; 3. a descending 

 artery which supplies the popliteus and passes through between 

 the tibia and fibula to the anterior tibial muscles. 



The posterior tibial artery continues the popliteal. It gives 

 off a recurrent branch which anastomoses with the geniculars. 

 A long branch, corresponding to the human anterior tibial 

 artery, descends to the lower end of the posterior tibial region 

 and curves forwards to the anterior tibial region ; it gives off 

 the following branches: — 1. an artery which anastomoses with 

 the saphenous artery and helps to form the arterial arcade on the 

 dorsum of the foot ; 2. muscular arteries ; 3. malleolar arteries ; 

 4. nutrient artery to the fibula ; 5. articular arteries to the 

 ankle. The arterial arch on the dorsum gives digital arteries to 

 all toes except the hallux. The saphenous artery, after forming 

 the arterial arcade, supplies the tarsal joints and gives an artery 

 which replaces the dorsalis pedis in Man. This dips in between 

 the hallux and first toe and gives a branch to the lateral side 

 of the hallux and several muscular arteries. It then passes 

 between the heads of the adductor hallucis and anastomoses with 

 the deep branch of the lateral plantar artery to form the plantar 

 arch. The latter vessel is the terminal branch of the posterior 

 tibial artery. 



The posterior tibial arteiy divides under the laciniate ligament 

 into medial and lateral plantar arteries. The lateral plantar 

 artery gives off the lateral calcanean artery to the skin of the 

 heel and branches to the flexor brevis digitorum, accessorius, 

 and abductor minimi digiti. It then divides into superficial
