Uberon definition : 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];
Uberon Homology note : 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];
