Which of the following about the urinary bladder is correct?
A. Reflex activation of the parasympathetic innervation of the detrusor during filling
prevents bladder contraction and facilitates storage
B. Both the internal and external sphincters must remain closed during filling for
continence.
C. The sympathetic innervation of the lower urinary tract passes to the bladder via the
pudendal nerves.
D. In detrusor sphincter dyssynergia (DSD), hyperreflexic bladder contractions are
synchronized with external sphincteric relaxation, but internal sphincter contraction
occurs.
E. In cauda equina injury, bladder control is impaired, but ano-rectal function is
preserved.
F. Detrusor hyperreflexia may be associated with urge, but not stress, incontinence
G. none of the above
explain pls.
