Visualizing the position of major
Each of the vertebral levels in the abdomen is related to the origin of major blood vessels (Fig. 4.180):
The celiac trunk originates from the aorta at the upper border of the LI vertebra.
The superior mesenteric artery originates at the lower border of the LI vertebra.
The renal arteries originate at approximately the LII vertebra.
