The urorectal septum is a coronal wedge of mesenchyme between the allantois and the hindgut.As it grows toward the cloacal membrane,it produces infoldings of the lateral walls of the cloaca.When these infoldings fuse,they divide the cloaca into the rectum dorsally and the urogenital sinus ventrally.The urorectal septum also divides the cloacal membrane into the anal membrane and the urogenital membrane.The area of fusion of the urorectal septum with the cloacal membrane becomes the perineal body (tendinous center of perineum).
