Psoas parvus is longer and thinner tlian psoas magnns. 

 Its fibres from the lateral part of the bodies of the last 

 three dorsal and the anterior liJinbar vertebrae converge 

 to form a tendon, which becomes inserted into the brim of 

 the pelvis midway between the antero -inferior spinous 

 process of the ilium and the acetabulum. 



Quadratus lumborum is attached to the last rib, and to 

 the transverse process of all the lumbar vertebrae running 

 to the venter ilii near the crista. 



Intertransversales lumborum are situated between the 

 transverse processes of the lumbar vertebraa. 



The psoas faschia covers the under surface of the psose 

 muscles. It affords attachment to transversalis abdominis 

 and obliquus abdominis internus, and from it in some sub' 

 jects arise sartorius and cremaster muscle.
