other gluteals. It is supplied by a large branch from the crural 

 plexus. 



Gluteus quartrus. — This small muscle lies between the last two 

 muscles, from both of which it is quite distinct, though partially 

 overlapped and concealed by them. It arises fleshy from the 

 lower edge of the ileum between the minimus and the acetabulum. 

 Its insertion is by a broad tendon to the femur between the in- 

 sertions of the medius and minimus. Its nerve is a V-b ranch of 

 the crural plexus.

Pectinens. — This is a small, round, entirely fleshy muscle, arising 

 between the origin of the gluteus quartus above and that of the

 anterior inner face of the femur below the head.
