<prompt> TRUE about anal membrane:Perforates at 6 weeksDevelops from anterior pa of cloacal membraneLies at proximal pa of proctodaeumCovers urogenital sinus  <response>: Anal membrane develops from posterior not anterior pa of cloacal membrane, lies at proximal pa of proctodaeum and covers primitive rectum not urogenital sinus. During development, cloaca at distal end of hindgut is covered by cloacal membrane which has two pas. Urogenital membrane is the ventral anterior pa to cover primitive urogenital sinus. Anal membrane is the dorsal posterior pa to cover primitive rectum. Anal membrane perforates at 9th week to let open the gut tube to the exterior at proctodaeum.
