THE MUSCLES. 



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

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

 the opposite side — origin. 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 



MUSCLES OF THE STJBLUMBAR, PATELLAR, AHD INTERNAL CRURAL REGIONS.

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.
