A patient has a spinal cord injury affecting parasympathetic supply to the bladder. Which change is most likely?
Correct answer: B. Bladder emptying becomes impaired
- A. The detrusor muscle contracts continuously
- B. Bladder emptying becomes impaired
- C. The kidneys stop producing filtrate
- D. The ureters become completely obstructed
Explanation
Parasympathetic activity contracts the detrusor muscle during micturition. Damage to this pathway can impair bladder emptying, although urine formation by the kidneys may continue.
