Q1. Where is the base of a renal pyramid located?
- At the ureteric opening
- Outside the renal capsule
- Inside the renal pelvis
- At the corticomedullary junction facing the cortex
Q2. Which vessels run near the bases of renal pyramids?
- Arcuate vessels
- Gonadal vessels
- Hepatic vessels
- Inferior phrenic vessels
Q3. How does a renal pyramid relate to a renal lobe?
- A pyramid forms the renal capsule
- A pyramid forms the medullary core of a renal lobe
- A pyramid is identical to a major calyx
- A pyramid lies outside the renal lobe
Q4. Which part of a renal pyramid contains the terminal papillary ducts?
- The renal hilum
- The apical papillary region
- The cortical labyrinth
- The fibrous capsule
Q5. What is the area cribrosa?
- The origin of the renal artery
- The perforated surface at the papillary apex
- The outer renal capsule
- The base of a renal column
Q6. Why are renal corpuscles absent from renal pyramids?
- Renal corpuscles are cortical structures
- Pyramids contain no nephron components
- Renal corpuscles are found only in the renal pelvis
- All glomeruli lie within minor calyces
Q7. Which nephron type contributes the longest loops extending through renal pyramids?
- Superficial cortical nephrons only
- Renal corpuscles
- Collecting ducts
- Juxtamedullary nephrons
Q8. What is the relationship of medullary rays to renal pyramids?
- They are branches of the renal pelvis
- They extend from pyramids into the cortex
- They are spaces filled with renal sinus fat
- They form the fibrous capsule
Q9. How does urine leave a renal pyramid?
- Through renal columns into the renal vein
- Through papillary ducts at the papilla into a minor calyx
- Through glomeruli into the renal artery
- Through the capsule into perirenal fat
Q10. Why can the number of renal pyramids vary among individuals?
- Every kidney develops exactly one pyramid
- Developmental variation in renal lobes and their fusion
- Their number is determined by the renal vein
- Pyramids form randomly after birth
