Questions and Answers

What is the pressure produced by the muscular contraction in the bladder wall?

  • 50 cmH2O
  • 200 cmH2O
  • 100 cmH2O
  • 150 cmH2O (correct)
  • How does the bladder wall's muscular contraction lead to pressure?

  • By shrinking the bladder
  • By generating a momentary pressure increase (correct)
  • By expanding the bladder
  • By causing a momentary pressure drop
  • What effect does the sizable muscular contraction have on the bladder wall?

  • Increases flexibility
  • Decreases capacity
  • No effect
  • Produces momentary pressure (correct)

    Study Notes

    Pressure in the Urinary Bladder

    • The internal pressure in the bladder is caused by the accumulation of urine.
    • The pressure-volume curve for the bladder shows that the bladder stretches as the volume increases.
    • The typical maximum volume in the bladder before voiding is 500 ml for adults.
    • At a pressure of approximately 30 cm H2O, the micturition reflex occurs.
