It arises below the symphysis pubis, and is in-

 tially beneath the insertion of the sartorius. (Plate 

 IV.) 



Reflect the gracilis muscle. 



14. The Adductor is a large muscle arising from 

 the pubis and ischium, near the symphysis, and 

 below the origin of the gracilis. It is inserted on 

 the posterior part of the femur, along the linea 

 aspera. (Plates III. and IV.) 



15. The Pectineus is a small, thin muscle, arising 

 from the pubis, near the symphysis. It is inserted 

 on the ridge between the lesser trochanter and the 

 linea aspera of the femur, and also on the linea 

 aspera itself. (Plate IV.) 



1 6. The Psoas Magnus is the large, cylindrical 

 muscle lying along the dorsal wall of the abdom- 

 inal cavity. It arises from the transverse processes 

 of the lumbar vertebrae, and passes out beneath 

 the brim of the pelvis. It is inserted on the lesser 

 trochanter of the femur. (Plate IV.) 



MUSCLES OF THE NECK. 



i. The Sterno-mastoid Muscle is a long, narrow 

 band which arises from the side of the manu-
