Q1. Why can occlusion of a renal segmental artery produce a localized area of ischemia?
- They are functionally end arteries with limited collateral flow
- They supply only the renal capsule
- They carry venous rather than arterial blood
- They all terminate in the renal pelvis
Q2. Which embryologic process helps explain the common occurrence of accessory renal arteries?
- Failure of the diaphragm to close
- Fusion of the gonadal arteries
- Rotation of the midgut
- Persistence of arteries acquired during renal ascent
Q3. Why is an accessory renal artery usually important to preserve during renal surgery or transplantation?
- It may supply a distinct renal territory with limited collateral flow
- It drains the kidney into the inferior vena cava
- It can be removed without affecting renal perfusion
- It always supplies only perirenal fat
Q4. Which renal arterial branch directly precedes the arcuate arteries in the intrarenal arterial sequence?
- Afferent arteriole
- Cortical radiate artery
- Interlobar artery
- Segmental artery
Q5. Which arteries arise from the arcuate arteries and extend into the renal cortex?
- Segmental arteries
- Cortical radiate arteries
- Interlobar arteries
- Lumbar arteries
Q6. Which vessels arise from cortical radiate arteries and deliver blood to individual renal corpuscles?
- Arcuate veins
- Vasa recta only
- Afferent arterioles
- Efferent veins
Q7. During surgery near the right renal artery origin, which major venous structure creates an important anterior relationship?
- Inferior vena cava
- Portal vein
- Splenic vein
- Left renal vein
Q8. How can an inferior polar artery contribute to ureteropelvic junction obstruction?
- By entering the urinary bladder wall
- By passing through the ureteral lumen
- By crossing and compressing the ureteropelvic junction
- By obstructing the renal vein from within
Q9. Which statement best describes renal arterial segmentation?
- Segmental arteries freely cross every segmental boundary
- Renal segments are defined only by venous drainage
- Each vascular segment is supplied by a segmental artery
- All segments receive identical branches from one arcuate artery
Q10. A surgeon traces arterial flow from the abdominal aorta toward a glomerulus. Which sequence is correct?
- Renal, segmental, interlobar, arcuate, cortical radiate, afferent arteriole
- Renal, lumbar, gonadal, arcuate, afferent arteriole
- Renal, arcuate, segmental, interlobar, afferent arteriole
- Renal, cortical radiate, interlobar, arcuate, segmental
