Editing Functional: Neural Control of Storage and Voiding (section)

=== Storage reflexes ===
* See [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897743/figure/F5/ Figure 5a] for storage reflex
* '''Also known as “guarding reflex”, “spinal reflex”, “spinal reflex pathway”, “bladder sympathetic reflex”'''
* '''<span style="color:#ff0000">Promotes continence</span>'''
** '''During the storage of urine, distention of the bladder produces low-level bladder afferent firing via Aδ-myelinated nerves'''
** '''There is a gradual increase in proximal urethral pressure during bladder filling''', contributed to at least by the striated sphincteric element and perhaps by the smooth sphincteric element as well.
** '''<span style="color:#ff0000">Afferent stimulation, in turn, results in efferent(2):</span>'''
**# '''<span style="color:#ff0000">Sympathetic outflow resulting in</span>'''
**## '''<span style="color:#ff0000">Excitation (contraction) of bladder base and urethra</span>'''
**## '''<span style="color:#ff0000">Inhibition (relaxation) of bladder</span>'''
**# '''<span style="color:#ff0000">Pudendal outflow to the EUS</span>'''
**#* The increase in urethral pressure seen during the filling/storage phase of micturition can be correlated with an increase in efferent pudendal nerve impulse frequency and gradual increase in striated sphincter activity.
