Ans :-) This can be understand as :-

The external ear receives sound waves and directs them to ear drum.

The ear drum vibrates in response to sound waves.

These vibrations are then transmitted through ear ossicles to oval window.

The vibrations are passed from oval window on to the fluid of cochlea, where they generate waves in lymph.

The waves in lymph induces ripple in basiliar membrane. These movements of basiliar membrane bend the hair cells, pressing them against the tectorial membrane. As a result nerve impulses are generated in associated afferent neurons.

These impulses are transmitted by afferent nerve fibres via auditory nerves to the auditory cortex of brain where the impulses are analysed and sound is recognised.

Disorder of ear :- Meniere 's disease

It is disorder of inner ear that can lead to dizzy spells and hearing loss. In most cases, this disease affect only one ear. This disease can occur in any age but it usually starts in age between young and middle age adulthood.
