great trochanter will be raised ; this produces internal 

 rotation of the shaft of the femur. The iliopsoas and pec- 

 tineus have this action. 



Adductor Longns. Figs. 117, 119. 



Origin. From the front of the body of the pubes just 

 under the crest. 



Insertion. At the middle third of the femur, into the 

 inner lip of the linea aspera. 



Nerve Supply. The obturator nerve through its anterior 

 division. 



Action. To adduct, flex, and rotate the femur outward. 

 If the femur is the fixed point, it will flex the pelvis and 

 rotate it to the same side. 



Grracilis. Figs. 117, 119. 



Origin. From the inner margin of the rami of the pubes 

 and ischium, and from the lower half of the symphysis 

 pubis. 



Insertion. By a long slender tendon into the inner sur- 

 face of the tibia in the angle formed by the tendon of the 

 sartorius. 



Nerve Supply. A branch from the anterior division of the 

 obturator nerve. 



Action. To adduct the thigh, to flex the leg ; when the 

 leg is flexed to rotate it internally. 



The Internal Saphenous Nerve. Figs. 117, 119. 



The longest branch of the anterior crural nerve. Be- 

 ginning just below Poupart's ligament where the anterior 

 crural nerve breaks up into its terminal branches, the inter- 

 nal or long saphenous nerve descends along the outer side 

 of the femoral artery through Scarpa's triangle, then enters 

 Hunter's canal with the femoral vessels. In the canal the
