3 lis 2023 · The middle ear is a complex system of openings and canals placed mostly within the temporal bone. Its function is to transfer vibrations of the tympanic membrane into sound waves and pass them to the internal ear. The middle ear is made up of the tympanic cavity and epitympanic recess.
27 lis 2023 · The middle ear is an air-filled space within the temporal bone which lies between the tympanic membrane laterally and the inner ear medially. It contains 3 ossicles which connect the tympanic membrane to the inner ear at the oval window.
The tympanic membrane, or eardrum (tympan/o, myring/o), is a shiny, oval, semitransparent membrane that lies at the end of the external auditory canal and at the entry to the middle ear. Within the middle ear cavity are three small bones, or ossicles (ossicul/o): the malleus, incus, and stapes (staped/o)—so named because they resemble a ...
