Urinary System Test Questions And Answers Questions
Question 1 of 5
The presence of glucose in urine is called:
Correct Answer: B
Rationale: Glycosuria is glucose in urine not proteinuria (protein), hematuria (blood), or pyuria (pus). This identifies diabetic marker, key for diagnosis, contrasting with other abnormalities.
Question 2 of 5
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.
Question 3 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 4 of 5
The macula densa is characterized by all of the following EXCEPT
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.
Question 5 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.
