| Preferred Name | pharyngotympanic tube |
| Definitions |
Organ with organ cavity which connects the cavity of the middle ear to the cavity of the pharynx. Examples: There are only two pharyngotympanic tubes, the right and the left pharyngotympanic tubes.[FMA].
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

| Synonyms |
eustachian tube
tuba pharyngotympanica
tuba auditiva; tuba auditoria; tuba auditivea
pharyngo-tympanic tube
auditory tube
tuba auditoria
internal auditory tube
tuba auditiva

| 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.[uncertain][VHOG]
