THE MUSCLES. 



Attachments. — It originates, by the whole extent of its superior border, from 

 the under surface of the ischio-pubic symphysis, aud is united to the muscle of 

 the opposite side— on^m. Its terminal aponeurosis, united to that of the sar- 

 torious, is inserted on the internal patellar ligament and the internal face of the 

 tibia — movable insertion ; posteriorly, it is united to the aponeurosis of the semi- 

 tendinosus, and with it forms the tibial aponeurosis enveloping the tibial muscles. 



Relations. — Its superficial face is covered by a cellulo-fibrous layer, and by 

 the saphena vessels and nerves. It covers, by its deep face the pectineus, the

adductors of the thigh, the semimembranosus and semitendinosus, and the 

 internal femoro-tibial ligament. It is traversed at its origin, and altogether in 

 front, by a very large vein. 



Action. — An adductor of the limb and a tensor of the tibial aponeurosis.
