A person sustained blunt force trauma to the back at the T5 level, with no spinal cord injury. Would you suspect the kidneys to be damaged? • A. Yes, because they lie between T3 and T8. • B. Yes, because they are directly adjacent to T5. • C. No, because the kidneys lie lower, between T12 and L3. • D. No, because they are protected by the pelvic girdle. • Correct Answer: C • Rationale: The kidneys are anatomically situated between the T-12 and L-3 vertebrae. Q2: What is the primarily noted structure and purpose of the renal capsule? • A. It is a muscular sheath that pumps blood into the renal hilum. • B. It is a protective layer that protects the kidney from injury and infection. • C. It is a mucosal layer that produces mucus to lubricate urine flow. • D. It is a network of capillaries where blood filtration begins. • Correct Answer: B • Rationale: The renal capsule serves as a protective barrier to shield the kidney from trauma and infectious agents. Q3: Which fatty layer lies outside of the renal capsule to protect the kidney from trauma? • A. Renal capsule • B. Renal adipose capsule • C. Renal fascia • D. Peritoneum • Correct Answer: B • Rationale: The renal adipose capsule is the specific fatty layer outside the renal capsule that cushions the kidney from trauma. ________________________________________ 2. Renal Vasculature Q4: Which of these blood vessels flow directly in between the renal pyramids? • A. Afferent arterioles • B. Lobar arteries • C. Interlobar arteries • D. Arcuate arteries • Correct Answer: C • Rationale: Interlobar arteries are the specific vascular branches that run between the renal pyramids. Q5: Interlobular veins converge directly to form which of the following vessels? • A. Efferent arterioles • B. Lobar veins • C. Arcuate veins • D. Peritubular capillaries • Correct Answer: C • Rationale: Venous return from interlobular veins flows directly into the arcuate veins. ________________________________________ 3. Bladder & Urethra Q6: Which of the following is true concerning the anatomical location of the urinary bladder in females? • A. The bladder sits directly above the uterus. • B. The vagina is located behind the bladder. • C. The rectum is anterior to the bladder. • D. The bladder is posterior to the uterus. • Correct Answer: B • Rationale: In females, the vagina lies posterior to (behind) the urinary bladder. Q7: Which two features of the bladder specifically allow for its internal expansion and capacity? • A. Rugae (wall folds) and transitional epithelium • B. Microvilli and columnar cells • C. Stratified squamous cells and major calyces • D. Elastic cartilage and external sphincters • Correct Answer: A • Rationale: Rugae are wall folds that extend to increase capacity, and specialized transitional epithelial cells expand to absorb fluid pressure. Q8: An elderly male patient is unable to micturate. What is the most likely pathological cause? • A. Urinary retention due to spinal cord injury • B. Urinary retention due to an enlarged prostate • C. Incontinence due to end-stage dementia • D. Hematuria due to diabetes • Correct Answer: B • Rationale: An enlarged prostate commonly compresses the urethra in elderly males, leading to urinary retention. Q9: What is the smallest region of the male urethra? • A. Spongy • B. Prostatic • C. Membranous • D. Ejaculatory duct • Correct Answer: C • Rationale: The membranous urethra is the smallest segment of the male urethral passage. Q10: Which region of the male urethra directly exits the bladder?
