Neuroanatomy: Overview of Functional Signaling Pathways
The lower urinary tract requires intact and appropriate neurological control in order to safely accommodate urine produced by the kidneys, and in order to maintain socially acceptable patterns of continence and voiding. Functional MRI has improved our understanding of the pathways in the brain that are involved in bladder control. Storage of urine is mediated by the sympathetic nervous system, while voiding is mediated by the parasympathetic nervous system. Progressive neurologic disease can lead to significant alterations in the neurologic control of the bladder and sphincter.
