Peritoneal folds related to the Spleen& Kidney:-
• Gastrosplenic ligament.
• Splenorenal (lienorenal) ligament:
connects the spleen to the posterior abdominal wall over the left kidney.

Ilio-psoas spaces
• The iliopsoas compartment consists of the psoas major, psoas minor, and iliacus muscles.
• The psoas major muscle arises from the transverse processes of the 12th thoracic and lumbar vertebrae
• merges with the iliacus muscle at the level of the L5 through S2 vertebrae to form the iliopsoas muscle.
