MUSCLES OF THE POSTEBIOB LIMBS. 361 



The pedineus repeats the anterior branch of the pectiueus of the Horse. It is inserted, 

 below, into the internal bifurcation of the linea aspera of the femur. 



The first adductor corresponds to the posterior branch of the pectineus of Solipeds. It is 

 represented by a voluminous muscular mass, which arises from the spine of the pubis and 

 terminates on the middle third of the linea aspera. 



The second or small adductor corresponds to the muscle of the same name in animals. It is 

 inserted into the same points as the preceding. 



The third or great adductor is attached, above, to the ischiatic tuberosity and to the whole

of the lower branch of the ischium by aponeurotic fibres. It afterwards divides into two 

 branches : the external branch, entirely muscular, is fixed into the entire interspace of the 

 linea aspera ; the internal branch gives rise to a tendon which goes to the inner condyle of the 

 femur. Between these two branches is found, as in the Horse, the ring of the adductors, in 

 which pass the large vessels of the thigh. 



The quadratus femoris of Man is nearly horizontal, as it is attached, inwardly, to the 

 external border of the ischium, and outwardly, between the great and small trochanters. 



The obturator internus and gemelli resemble those of the Dog.
