7. The adductor brevis : a little bit of it is seen 

 on the inner side of the adductor magnus, 

 close to the symphysis pubis. 



8. The rectus internus major: a large muscle 

 running along the whole inner side of the 

 thigh; arises from the symphysis pubis below 

 the sartorius and is inserted into the same 

 aponeurosis as that muscle. 



e. The rectus internus minor: a thin muscle lying 

 inside and rather behind the rectus internus 

 major. It arises from the pelvis close to the 

 anus and is inserted into the aponeurosis about 

 the knee-joint. 



The adductor longus: it is partly superficial 

 along the outer edge of the sartorius. 



ij. The vastus internus: a very large muscle on 

 the outer anterior aspect of the thigh ; arising 

 from the pelvis close to the hip-joint, it joins, 

 below, two muscles on the back of the thigh 

 (4. a. j3. 7), and all end in a tendon which is 

 inserted into the aponeurosis over the front of 

 the os cruris. 



e. Cut across the belly of the sartorius, and turn its 

 ends out of the way ; dissect out the origin and 

 insertion of the adductor longus and the adductor 

 magnus (d. f. and /3). 



a. The adductor longus arises from the anterior 

 inferior part of the symphysis of the iliac bones ; 

 by its lower end it joins the adductor inagnus. 



^. The adductor magnus, arises from the pelvis, 

 between the origin of the sartorius and that 

 of the rectus internus major. Its fibres are
