part_of starts_at ends_at urinary system pelvic ganglion EMAPA:31527 The pelvic ganglion (TS:19-TS:28): the pelvic ganglia provide autonomic innervation to the organs of the genitourinary system and lower bowel and are comprised of both sympathetic and parasympathetic neurons. In the mouse they are paired, morphologically discrete, major ganglia in the pelvic region positioned on either side of the urethra where the urethra meets the bladder neck. The pelvic ganglia are derived from the sacral neural crest progenitors that migrate ventrally from the level of somites X-Y ventrally into the urogenital sinus where they form aggregates between the hind gut and the urogenital sinus during organogenesis. In the GUDMAP database, the pelvic ganglia are considered part of the genitourinary system, although some of the sympathetic and parasympathetic neurons project instead to the lower bowel.
