Which of the following statements is INCORRECT

Correct Answer: B

Rationale: Efferent arterioles don't belong to the JGA (includes JG cells, macula densa, lacis cells) not incorrect are fenestrated endothelium, lacis in JGA, or podocytes on basement membrane. This corrects JGA composition, key for RAAS, contrasting with true glomerular traits.

Correct Answer: C

Rationale: Macula densa is in DCT, tall/dark cells, has a basement membrane not near urinary pole (vascular pole). This corrects position, key for JGA function, contrasting with pole error.

Correct Answer: B

Rationale: Fossa navicularis (distal urethra) has stratified squamous epithelium not transitional (bladder), pseudostratified, or stratified columnar. This defines urethral lining, critical for histology, contrasting with proximal urethra.

Correct Answer: D

Rationale: Bladder has transitional epithelium, three muscle layers, and partial peritoneum not stratified columnar, two layers, or adventitia only. This corrects bladder anatomy, critical for histology, contrasting with listed errors.

Correct Answer: B

Rationale: Male urethra has transitional epithelium near bladder (not typical in female) glands of Littre and squamous are in both. This corrects gender difference, key for urology, contrasting with shared features.
