interureteric ridge a fold on mucous membrane extending across the bladder between the ureteric orifices.
mammary ridge an ectodermal thickening in early embryos, along which the mammary glands subsequently develop.
mesonephric ridge the more lateral portion of the urogenital ridge, giving rise to the mesonephros.
oblique ridge a variable linear elevation obliquely crossing the occlusive surface of a maxillary molar.
urogenital ridge a longitudinal ridge in the embryo, lateral to the mesentery.

go·nad·al ridge

an elevation of thickened mesothelium and underlying mesenchyme on the ventromedial border of the embryonic mesonephros; the primordial germ cells become embedded in it, establishing it as the primordium of the testis or ovary.

genital ridge

A ridge that develops on the ventromedial surface of the urogenital ridge and gives rise to the gonads.

1) Testicular duplication where both testicles aroused from the same genital ridge and they have a common deferent duct and blood supply.
This can occur if there is complete transverse division through the genital ridge and the mesonephros.
This may result if the division of the genital ridge does not include the mesonephros.
Currently, the most accepted one is represented by division of the genital ridge by peritoneal bands, in either transverse or longitudinal orientation.
Early development of the ovary is characterised by segregation and migration of the primordial germ cells from their sites of origin to the genital ridges (bilateral thickenings of the coelomic epithelium).
5 dpc genital ridges were isolated and transplanted to adult mice recipients previously treated with Busulfan, to probe the formation of minitubules in the receptors.
