THE ANTERIOR TIBIAL ARTERY. 253 



sels form an anastomosis below the great trochanter of 

 the femur ; (c) the Three Perforating, perforate the ad- 

 ductor magnus. 



Muscular. To muscles of thigh. 



Anastomotica Magna. Is given off on a level with 

 the lower third of the thigh, just before the femoral 

 enters Hunter's canal, which is an oblique canal through 

 the adductor magnus, close to the inner side of the femur. 

 The anastomotica magna supplies the integument and 

 inosculates with the recurrent tibial. As the femoral 

 passes through the adductor magnus, it becomes the 

 popliteal and runs down through the popliteal space. 



POPLITEAL ARTERY. 



The popliteal artery is the continuation of the femoral, 

 and begins at the opening in the adductor magnus mus- 

 cle. It lies deep in the popliteal space, and sends off : 



Superior External Articular. Winds around the 

 femur, supplies muscles, and forms free anastomoses. 



Superior Internal Articular. Winds around the 

 femur, supplies muscles, and forms free anastomoses. 



Inferior External Articular. Winds around the 

 tibia, supplies muscles, and forms free anastomoses. 



Inferior Internal Articular. Winds around the 

 tibia, supplies muscles, and forms free anastomoses. 



Azygos Articular. Supplies ligaments and synovial 

 sac of knee-joint. 



Cutaneous. Supplies skin of calf of leg. 



Muscular. Supplies muscles of popliteal region. 

 At the lower border of the popliteal muscle the popliteal 

 artery divides into the anterior and posterior tibial. 



THE ANTERIOR TIBIAL ARTERY. 



The anterior tibial artery passes through the foramen, 

 in the upper part of the interosseous membrane, runs
