Voiding Dysfunction Flashcards
what parasymp receptor mediates bladder control?
M3/M2
what does sympathetic activation do at bladder?
allows for filling via relaxation of the SM
what is the sympathetic receptor in the bladder?
B3
what is the sympathetic in charge of with the bladder outlet and internal urethra?
contraction
what sympathetic receptor is in charge of the bladder outlet contraction and urethral contraction?
alpha receptors
what does the somatic nervous system control with the bladder?
external sphincter
what is the cerebral micturition center in charge of?
telling bladder not to activate…really controls when you go
what is the pontine micturition center in charge of?
helps with coordination of activities with the sphincters and bladder
what is the sacral micturition center in charge of?
processes afferent signals and routes efferent signals
what does bladder overactivity mean?
bladder contracts when we dont want it to
what are symptoms of bladder overactivity?
urinary urgency and frequency with urge incontinence
what is issue in decreased storage volume of bladder?
decreased capacity to fill..you get afferent receptors activating earlier at lower volumes
what are symptoms of decreased storage volume?
urgency and frequency
what is issue with a stiff bladder?
you have low compliance of the bladder
what is the cause of stress incontinence?
weak or damaged sphincter muscles that lapse when cough or sneezing
what are two ways to limit bladder emptying?
