Urogenital membrane

Cloacal membrane

The cloacal membrane is the membrane that covers the embryonic cloaca when still in the development of the urinary and reproductive organs.

It is formed by ectoderm and endoderm coming into contact with each other. After separation of the cloaca into the urogenital and anal parts, the cloacal membrane, in turn, is separated into a urogenital membrane and an anal membrane.
