Urinary System Multiple Choice Questions Questions
Question 1 of 5
Podocytes are
Correct Answer: D
Rationale: Podocytes are visceral epithelial cells of Bowman's capsule, forming filtration slits not endothelial (capillaries), parietal (outer layer), or mesangial (support). This identifies their role in the filtration barrier, critical for GFR, contrasting with other glomerular cells.
Question 2 of 5
Mesangial cells
Correct Answer: D
Rationale: Mesangial cells phagocytose basement membrane not restricted (extra-glomerular exist), parietal (podocytes), or creatinine-secreting. This specifies their role, critical for GBM maintenance, contrasting with incorrect functions.
Question 3 of 5
Lacis cells are
Correct Answer: B
Rationale: Lacis cells are extra-glomerular mesangial cells in the JGA not secretory, intra-glomerular, or neuroepithelial. This specifies their identity, key for JGA support, contrasting with other cell types.
Question 4 of 5
Which matched pair is INCORRECT
Correct Answer: B
Rationale: Renin is from afferent not efferent arterioles; other pairs (macula/DCT, fenestrae/glomerulus, collecting/ray) are correct. This corrects renin source, key for RAAS, contrasting with true associations.
Question 5 of 5
Which association is CORRECT?
Correct Answer: C
Rationale: Macula densa has basal Golgi not PCT (brush), DCT (no brush), or efferent (renin in afferent). This identifies correct pair, key for histology, contrasting with misassociations.
