Anatomical Variations of Lumbar Arteries and Their Clinical Implications: A Cadaveric Study

Figure 6

A cadaver demonstrating the posterior abdominal wall structures of the left side of the body. In this specimen, the first and second lumbar arteries on the left side of the body pass posterior to the left crus of the diaphragm. This specimen also demonstrates that the third lumbar artery passes laterally on the vertebral body close to the intervertebral disc. A: left crus of the diaphragm. B: abdominal aorta. C: first lumbar artery. D: second lumbar artery. E: third lumbar artery. F: fourth lumbar artery. G: lumbar intervertebral disc between second and third lumbar vertebral bodies. H: third lumbar vertebral body. I: psoas major muscle.
