Middle Ear
malleus (hammer)- Receives the vibration from tympanic membrane and transmits this to the Incus.
Incus (anvil)- Transmits the vibrations to the Stapes
Stapes (stirrup) - Transmits the vibrations to the inner ear
Inner Ear
Oval Window - The vibration from the stapes enters the Social Vestibuli along with fluid
Scala Vestibuli- Conducts the sound vibrations into fluid
Vestibular Membrane- Separates the Endolymph and Perilymph.
Cochlear Duct - Filled with the Endolymph
Basilar Membranea- Vibrates the Organ of Corti from the sound wave
Organ of Corti- Hears the actual sound
Tectorial Membrane- Bends hairs of Organ of Corti from the vibrations of the Basilar Membrane.
Scala Tympani- Allows vibrations to escape the round window
