THE MUSCLES. 



of that bone. This tendon, with that of the sartorius, forms the aponeurotic expansion 

 called the goose's foot. 



The semimembranosus is voluminous in its lower portion, and arises, like the other 

 two, from the tuberosity of the ischium; its fibres pass to a tendon which, on reaching 

 the inner side of the knee, terminates in the three pieces composing that articulation (see 

 fig. 134).

C. Muscles of the Internal Region. 



In books on human anatomy, these muscles are sometimes designated, from their 

 action, by the generic name of adductors. They comprise : the internal rectus, pectineus, 

 first or middle adductor, second or small adductor, and third or great adductor. The 

 square crural, the obturators, and the gemelli are described among the posterior muscles 

 of the pelvis. They will, however, be briefly alluded to here. 



The internal rectits corresponds to the short adductor of the leg of animals. It is 

 a thin muscle, bordering the inner side of the thigh. It is attached, above, to the 

 symphysis pubis ; below, to the crest of the tibia, in common with the sartorius tendon.
