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 circumflex, 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 

 adductor 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 arti- 

 cular 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 gastrocnemius muscle. 



ANTERIOR TIBIAL ARTERY. 



The anterior tibial artery passes forwards between the two heads 

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