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

 called the goose's /oot. . , . i-i ii, ii. 



The semimemhranosus is volmninous 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 Imman anatomy, these muscles are sometimes designated, frnmi^fiir 

 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. Tlie 

 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 rectus coiTesponds to the short adductor of the leg of animals. It is 

 a thin muscle, bordeiing 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.
