MYOLOGY 





tened, and is inserted into the upper part of the medial surface of the body of the 

 tibia, below the condyle. A few of the fibers of the lower part of the tendon are 

 prolonged into the deep fascia of the leg. At its insertion the tendon is situated 

 immediately above that of the Semitendinosus, and its upper edge is overlapped 

 by the tendon of the Sartorius, with which it is in part blended. It is separated 

 from the tibial collateral ligament of the knee-joint, by a bursa common to it and 

 the tendon of the Semitendinosus.

The Pectineus (Fig. 430) is a flat, quadrangular muscle, situated at the anterior 

 part of the upper and medial aspect of the thigh. It arises from the pectineal line, 

 and to a slight extent from the surface of bone in front of it, between the 

 iliopectineal eminence and tubercle of the pubis, and from the fascia covering the 

 anterior surface of the muscle; the fibers pass downward, backward, and lateral- 

 ward, to be inserted into a rough line leading from the lesser trochanter to the 

 linea aspera. 



The Adductor longus (Fig. 433), the most superficial of the three Adductores, 

 is a triangular muscle, lying in the same plane as the Pectineus. It arises by a 

 flat, narrow tendon, from the front of the pubis, at the angle of junction of the crest
