The urogenital sinus arises from the posterior end of the cloaca during embryonic development, which eventually divides into the urinary and reproductive tracts. It does not give rise to the anus or rectum, and while the ureters connect to the bladder derived from the urogenital sinus, they themselves do not originate from it.
