Answer

Answer

Normal voiding is essentially a spinal reflex modulated by the central nervous system (brain and spinal cord), which coordinates function of the bladder and urethra. The bladder and urethra are innervated by 3 sets of peripheral nerves arising from the autonomic nervous system (ANS) and somatic nervous system. The central nervous system is composed of the brain, brain stem, and the spinal cord.
