EDITOR_NOTE we follow FMA in making this an organ, but include a separate class for the part that is epithelium, which is equivalent to the EHDAA2 structure. From this we infer the developmental relationship
The narrow channel connecting the nasopharynx and the middle ear. [TFD][VHOG]
Furrow on the ventral surface of the otic capsule, and occasionally also the parasphenoid, that houses the Eustachian tube.[AAO]

eustachian tube
tuba auditiva; tuba auditoria; tuba auditivea
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.[uncertain][VHOG]
