of the tbio-b, behind the feraui*, and disappears in tlie 

 crural mnscles. 3 — The superficial muscular, or great 

 anterior muscular, runs downwards, outwards and for- 

 wards, passing between the sartorius, psoas-magnus and 

 iliacug muscles, then between the vastus internus and 

 the straight anterior muscles, and terminates in the 

 triceps cruralis. 4 — A number of innominated branch- 

 es, or small muscular, amongst them the nutritive of 

 the femur. 5 — The saphena runs between the two 

 adductors of the leg to the internal face of the limb, 

 or to the surface of the gracilis, where it terminates 

 in two small branches. 



Popliteal. — Continuation of the femoral ; it di- 

 rects its course downwards between the bodies of the 

 bifemoro calcaneus, under the popliteus muscle and at 

 the tibial arch terminates in the posterior and anterior 

 tibial. Collateral branches : 1 — femoro-popliteal, with 

 its ascending and descending terminal ramifications ; 

 2 — articular branches ; 3 — muscular branches. 



Posterior tibial. — Situated under the popliteus, 

 the oblique and deep flexors of the phalanges, it runs 

 down to the hock joint and becomes more and more 

 superficial ; near the os calcis it runs through the tibial 

 aponeurosis, passes into the tibial arch and at the as- 

 tragalus ends in the plantar arteries. Collateral 

 branches : 1 — musculo-tibial branches ; 2 — the medul-
