Document Summary

* the posterior abdominal wall needs filling in from the 12th rib above which is the inferior aspect of the thorax behind to the posterior half of the iliac crest below and the lumbar vertebral column medially. The posterior abdominal wall structures will bridge this gap. * psaos major muscle: edge to edge with the lumbar vertebral column moving either side are a pair of psaos major muscles that may or may not have a psaos minor muscle overlying it. * quadratus lumborum muscle: edge to edge with psaos major there is a rectangular muscle. * iliacus muscle: inferior to quadratus lumborum but still edge to edge with psaos major. * the thoracolumbar fascia is associated with these muscles. * psaos major: lies in the gutters between the bodies and transverse processes of the lumbar vertebrae. So, psaos major lies edge to edge with the lumbar vertebral column, overlying the lumbar transverse processes.
