comment

each membrane is initially composed of an inner layer formed by the endodermal lining of a branchial pouch and an outer layer formed by the ectodermal lining of the branchial groove; later, these two layers become separated by a thin layer of mesoderm; only the first branchial membrane contributes to the formation of an adult structure, i.e. the tympanic membrane (aka eardrum); the second, third, and fourth membranes are obliterated[MP]

homology notes

In all vertebrates, the endodermal epithelium lining each pouch contacts the surface ectoderm of the clefts to form a series of bilayered branchial membranes, that break down in fish to form the gill openings.[well established][VHOG]
