Hearing
- Organ of Corti: The sensory organ of hearing.
Impedance Matching (Function of Middle Ear)
- Lever action of the ossicles.
- Hydraulic action of the tympanic membrane.
Sound Transmission Pathway Sound energy → Air → External canal → Tympanic membrane → Ossicles → Cochlear fluid wave → Stimulation of the basilar membrane → Shearing of hair cells with the tectorial membrane → Rapid depolarization → Impulse carried along the auditory nerve → Central connections.
