 THE INNER SIDE OF THE THIGH, 

 AND MUSCLES ON THE INNER WALL 

 OP THE PELVIS. 



1, iliacus muscle; 2, part of the 

 psoas magnus muscle ; 3, obturator 

 internus, with its fibres converging to- 

 wards the lesser sciatic foramen ; 4, 

 pyriformis, with three heads of origin, 

 and its fibres converging towards the 

 great sciatic foramen ; 5, a part of the 

 lumbar aponeurosis covering the erector 

 spinse muscle ; 6, gluteus maximus ; 

 7, sartorius, 7', its tendon inserted 

 below the tuberosity of the tibia ; 8, a 

 part of the adductor longus ; 9, gracilis, 

 9', its insertion passing below that of 

 the sartorius ; 10, part of the adductor 

 magnus ; 11, semimembranosus ; 12, 

 semitendinosus, 12', its insertion, and 

 between 9' and 12' the tendon of the 

 semimembranosus passing to its in- 

 sertion in the inner tuberosity of the 

 tibia. 



This muscle is covered by the fascia 

 lata, the sartorius, and the femoral 

 vessels; the posterior surface rests 

 superiorly on the adductor brevis, 

 and inferiorly on the adductor mag- 

 nus. Externally it is separated by a 

 small interval from the pectineus, 

 and internally it is in apposition with 

 the gracilis. 



The adductor Irevis, thick 

 above and broad below, arises 

 by a narrow origin, about two 

 inches deep, in contact with that 

 of the gracilis, from the anterior 

 surface of the body, and the 

 descending ramus of the pubes ; 

 directed obliquely backwards and 

 outwards it is inserted by a 

 flat tendon into the whole of the 

 oblique line leading from the 

 small trochanter of the femur to 

 the linea aspera, immediately 

 behind the insertion of the pec- 

 tineus. 



The adductor brevis is concealed at its origin by the adductor longus and at its 

 insertion in part by the pectineus ; it rests on the adductor magnus, and by its deep 

 surface is in contact superiorly with the obturator externus. 



The adductor magnus muscle arises from a part of the body of the pubes
