100 ANATOMY AND PHYSIOLOGY 



Nerves. Lumbar and femoral. 



Surgical note. Disease of the lumbar vertebrae resulting in pus causes 

 psoas abscess. The pus often follows the muscle fibers downward and appears 

 below the inguinal ligament. 



(The psoas minor is a small muscle in front of the major.) 

 The transversalis fascia is a layer of loose connective tissue 

 which completely lines the muscles of the abdomen; it is continuous 

 with the iliac fascia on the iliacus muscle and with the pelvic 

 fascia below.
