Multiple Choice Questions On Urinary System Questions
Question 1 of 5
The cells of the visceral layer of renal corpuscle are called:
Correct Answer: B
Rationale: Podocytes form the visceral layer of the renal corpuscle not mesangial (support), extra-glomerular (lacis), or JG cells (arterioles). This identifies filtration cells, critical for GFR, contrasting with support/control cells.
Question 2 of 5
The thin segment of loop of Henle can be distinguished from the vasa recta by all of the following EXCEPT
Correct Answer: A
Rationale: Thin segment (squamous epithelium) and vasa recta (endothelium) differ in content (urine vs. blood), wall thickness, and nuclei not epithelium type (both squamous). This corrects distinction, key for histology, contrasting with other differences.
Question 3 of 5
Structures typically seen at the border between the renal cortex and medulla are
Correct Answer: C
Rationale: Arcuate arteries/veins lie at the cortex-medulla border not interlobar (medulla), interlobular (cortex), or intralobular (misnomer). This locates junction structures, key for circulation, contrasting with other levels.
Question 4 of 5
The arteriola recta vera arise from
Correct Answer: B
Rationale: Arteriola recta vera (true) arise from arcuate arteries not interlobar, afferent, or efferent. This corrects medullary circulation, key for concentration, contrasting with efferent spuria.
Question 5 of 5
Renal filtration barrier is composed of all of the following structures EXCEPT
Correct Answer: D
Rationale: Filtration barrier includes fenestrated endothelium, basal lamina, and filtration slits none excluded. This confirms barrier components, critical for selectivity, contrasting with exclusion errors.
