Questions and Answers

Which property of the urinary tract system allows the bladder to distend with urine while maintaining low intravesical pressures?

  • The ability of the bladder to contract with enough force and duration to expel all or most of stored urine
  • The ability to delay voiding until a socially acceptable time and place are found
  • The ability of the bladder to distend with urine while maintaining low intravesical pressures (correct)
  • Detrusor relaxation in response to beta-adrenergic stimulation

    • Which layer of the bladder secretes signaling molecules that provide input to the brain regarding bladder filling and messaging to the bladder muscle?

  • Urothelium (correct)
  • Propria
  • Trigone
  • Detrusor

    • How does the lamina propria contribute to normal bladder distensibility?

  • Secreting signaling molecules that provide input to the brain regarding bladder filling
  • Producing elastic fibers that allow the bladder to return to normal shape after voiding
  • Secreting signaling molecules that provide input to the brain regarding the need to void
  • Allowing smooth muscle cells to stretch slowly without inducing a contraction until emptying is initiated (correct)
