Study Notes
Inner Ear Structure
- The cochlea, resembling a snail shell, is the organ of hearing.
Middle Ear Function
- The middle ear functions to amplify and transmit sound vibrations to the inner ear.
Membranous Labyrinth
- Structures lined with the membranous labyrinth contain a clear fluid called endolymph.
Tympanic Membrane Function
- The tympanic membrane (eardrum) vibrates from sound waves, transmitting these vibrations to the middle ear.
Auditory Ossicles
- The malleus (hammer) is a bone that makes up the auditory ossicles in the middle ear.
Test your knowledge about the functions of the middle ear and inner ear, including sound transmission, protection from intense vibrations, and air pressure equalization. Learn about the auditory ossicles: the malleus, incus, and stapes.
