Explanation:

The human ear is the organ that used for earing. The ear is divided into three major parts which are the ear drum, middle ear and the inner ear. Based on their functions, these ear parts functions differently.

The inner ear: This is the innermost part of the ear which consists of the cochlea, the balance mechanism, the vestibular and the auditory nerves. The cochlea transforms sound waves into electrical impulse which are sent to the brain.

The ear drum: This is a thin, coned shaped that separate the outer ear from the middle ear. The ear drum functions by transmitting sound from air to the ossicles inside the middle ear and then to the oval window in the fluid-filled cochlea.

The middle ear: This is the part of the ear between the ear drum and oval window. The middle ear function by transmitting sound from the outer ear to the inner ear. The middle ear consist of three bones which are the hammer, the anvil and the stirrup.

Considering, at the organs of the corti, this is receptor organ for hearing and it is located in the mammalian cochlea.
