– These vibrations are transmitted through the middle ear ossicles (malleus, incus, and stapes) to the oval window.
– The oval window’s movement creates pressure variations in the fluid within the cochlea, which is a spiral-shaped structure in the inner ear.
– The cochlea contains the organ of Corti, which houses tiny hair cells. These hair cells are mechanoreceptors that are stimulated by the fluid movements.
– When stimulated, the hair cells generate electrical signals, which are then transmitted to the brain via the auditory nerve.
