Urinary System Test Questions And Answers Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The pronephros is developed from intermediate mesoderm in the:
Correct Answer: A
Rationale: Pronephros forms in the cervical region of intermediate mesoderm not thoracic, lumbar, sacral, or combined. This transient structure (week 4) regresses in humans, giving way to mesonephros. Its cranial location reflects early embryonic patterning, key for understanding nephric succession, contrasting with caudal regions.
Question 5 of 5
The ureteric bud is developed from:
Correct Answer: C
Rationale: Ureteric bud sprouts from the mesonephric duct not urogenital sinus, vesicourethral canal, paramesonephric duct, or cloaca. This origin drives metanephric induction, key for kidney formation, contrasting with unrelated structures.
