Branches. The branches of the popliteal artery are the 



Superior external articular, 



Superior internal articular, 



Azygos articular, 



Inferior external articular, 



Inferior internal articular, 



Sural. 



The Superior articular arteries, external and internal, wind 

 around the femur immediately above the condyles, to the front of 

 the knee-joint, anastomosing with each other, with the external cir- 

 cumflex, the anastomotica magna, the inferior articular, and the 

 recurrent of the anterior tibial. The external passes beneath the 

 tendon of the biceps, and the internal through an arched .opening 

 beneath the tendon of the abductor magnus. They supply the knee- 

 joint and the lower part of the femur. 



The Azygos articular artery pierces the posterior ligament of the 

 joint, the ligamentum posticum Winslowii, and supplies the synovial 

 membrane in its interior. There are frequently several posterior 

 articular arteries. 



The Inferior articular arteries wind around the head of the tibia 

 immediately below the joint, and anastomose with each other, the 

 superior articular arteries, and the recurrent of the anterior tibial. 

 The external passes beneath the two external lateral ligaments of 

 the joint, and the internal beneath the internal lateral ligament. 

 They supply the knee-joint and the heads of the tibia and fibula. 



The Sural arteries (sura, the calf) are two large muscular 

 branches, which are distributed to the two heads of the gastrocne- 

 mius muscle.

The anterior tibial artery passes forwards between the two heads 

 of the tibialis posticus muscle, and through the opening in the upper
