Which Arteries Provide a Good Landmark for Identifying the Corticomedullary

Question

Which arteries provide a good landmark for identifying the corticomedullary boundary?
A) cortical radiate arteries (interlobular arteries)
B) interlobar arteries
C) segmental arteries
D) arcuate arteries

Accepted Answer

The arcuate arteries, which are located at the border between the renal cortex and medulla, serve as a good landmark for identifying the corticomedullary boundary. These arteries arch over the base of the medullary pyramids, marking the transition between the cortical and medullary regions of the kidney.
