| Definitions |
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 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]. |

| 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] |
