tubotympanic recess

homology notes

The tympanic cavity and auditory tube of an amniote develop from the first embryonic pharyngeal pouch, so they are homologous to the first gill pouch, or spiracle, of a fish. We are uncertain whether this homology strictly applies to the middle ear cavity and auditory tube of lissamphibians, which show certain peculiarities in their development.[well established][VHOG]
