Uberon definition : The middle ear is the air-filled cavity within the skull of vertebrates that lies
between the outer ear and the inner ear. It is linked to the pharynx (and therefore
to outside air) via the Eustachian tube and in mammals contains the three ear ossicles,
which transmit auditory vibrations from the outer ear (via the tympanum) to the inner
ear (via the oval window)[GO].;
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];
