Kidneys, suprarenal glands and posterior abdominal vessels, nerves and muscles
Quadratus lumborum muscle with nerves and blood supply, anterior view
Attention is directed to the anterior aspect of the quadratus lumborum muscle with its nerve supply in a different specimen than that shown in the preceding view. The inferior vena cava has been removed, the lower part of the abdominal aorta has been cut away, and the left psoas muscle has been cleared of its fascia and detached from its origin.
