Development of the urinary and reproductive organs

As Urogenitalleiste ( Crista urogenital ) an elongated elevation on the dorsal wall of the coelomic cavity is referred to in embryology. It occurs on both sides of the median plane by proliferation of the so-called intermediate mesoderm ( Ursegmentstiel ), which thus bulges into the coelomic cavity. The Urogenitalleiste is the common primordium of various portions of the genito-urinary apparatus. The system of the kidneys, specifically the Vornieren - - as well as the genital ridge of the developing gonads and gonadal ligaments From it the nephrogenic cord differentiate.
