insertion of the gracilis and semitendinosus, but is separated 

 from them by a bursa. The sartorius is supplied by the 

 femoral nerve. It is a flexor of the knee and a medial 

 rotator of the leg, a flexor of the hip joint and a lateral 

 rotator of the thigh. 



Canalis Adductorius Hunteri (O.T. Hunter's Canal). 

 When the femoral artery leaves the femoral triangle it is con- 

 tinued distally, in the medial region of the thigh, in a deep 

 furrow, which is bounded anteriorly by the vastus medialis 

 muscle, and posteriorly by the fascia on the anterior surfaces of 

 the adductor longus and magnus muscles, which is the medial 

 intermuscular septum of the thigh. At its proximal end this 

 furrow is continuous with the deeper, wider, and more apparent

hollow, which has been described as the femoral triangle. 

 Further, the furrow is converted into a canal, triangular on 

 transverse section, by a strong fibrous membrane which stretches 

 across it, and upon the surface of which the sartorius muscle is 

 placed (Fig. 115). The tunnel thus formed is called the 

 adductor canal ( Hunter's). The fibrous expansion which roofs 

 in the canal stretches from the adductor longus and the 

 adductor magnus posteriorly to the vastus medialis anteriorly. 

 When it is traced proximally, it is seen to become thin and 

 ill-defined as it approaches the femoral triangle ; when traced 

 in the opposite direction, however, it becomes dense and 

 strong, and below the opening in the adductor magnus,
