-the middle ear is the portion of the ‘ear’ internal to the ‘eardrum’ + ‘external’ to the ‘oval window’ of the [inner ear]-
.
(the ‘mammalian middle ear’ contains 3 ‘ossicles’, which transfer the ‘vibrations’ of the ‘eardrum’ into ‘waves’ in the ‘fluid’ + ‘membranes’ of the ‘inner ear’)
(the ‘hollow space’ of the ‘middle ear’ is also known as the ‘tympanic cavity’ + is surrounded by the ‘tympani bone’)
(the ‘auditory tube’ (also known as the ‘eustachian tube’ or the ‘pharyngo-tympanic tube’) joins the ‘tympanic cavity’ with the ‘nasal cavity’ (‘naso-pharynx’), allowing pressure to equalize between the ‘middle ear’ + ‘throat’)
.
*the ‘primary function’ of the ‘middle ear’ is to efficiently transfer ‘acoustic energy’ from ‘compression waves’ in ‘air’ to ‘fluid–membrane waves’ within the ‘cochlea’*
