Urinary System Test Questions And Answers Questions
Question 1 of 5
All the following statements about the distal convoluted tubules are CORRECT EXCEPT:
Correct Answer: A
Rationale: DCT is ~5 mm long not 14 mm; other traits (diameter, portions, microvilli, mitochondria) are correct. This corrects DCT length, key for nephron mapping, contrasting with true histological features.
Question 2 of 5
Fossa navicularis is lined with
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.
Question 3 of 5
The urinary bladder
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.
Question 4 of 5
Which of the following structures is present in the male urethra but is NOT present in the female urethra
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.
Question 5 of 5
Collection of cortical tissues found between the pyramids are called:
Correct Answer: B
Rationale: Renal columns of Bertin are cortical tissue between pyramids not rays, interlobular, or none. This repeats Q4/Q30, key for anatomy, contrasting with other terms.
