Definition:	The membrane that covers the embryonic cloaca, formed by the union of proctodeal (anal pit) ectoderm and cloacal endoderm, with no intervening mesoderm; the urorectal septum joins the cloacal membrane and divides it into an anal membrane and a urogenital membrane; the point where the urorectal septum intersects the cloacal membrane is the future site of the perineal body; proliferation of mesoderm and ectoderm around the cloacal membrane produces primordial tissues of the external genitalia in both sexes: the genital tubercle, genital folds, and genital swellings.
Comment:	[homology-note] "In mammals, the cloaca exists as an embryonic structure that undergoes septation to become distinct urethral, anal, and genital orifices.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0001198", ontology="VHOG", source="PMID:11830557 De Santa Barbara P, Roberts DJ, Tail gut endoderm and gut/genitourinary/tail development: a new tissue-specific role for Hoxa13.
