Question

explain how human ear work with the help of a diagram

Answer 1

The three parts of the ear anatomy are the outer ear, the middle ear and the inner ear. The inner ear is also called the cochlea. (‘Cochlea’ means ‘snail’ in Latin; the cochlea gets its name from its distinctive coiled up shape.)

The outer ear consists of the pinna, ear canal and eardrum
The middle ear consists of the ossicles (malleus, incus, stapes) and ear drum
The inner ear consists of the cochlea, the auditory (hearing) nerve and the brain
Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain ‘knocks’ on the membrane window of the cochlea and makes the fluid in the cochlea move. The fluid movement then triggers a response in the hearing nerve

Answer 2

Our ear contains three parts..

<> the outer ear
<> the middle ear
<> the inner ear

=> The inner ear contains the Pinna, ear tube.
we know that sounds travel with the vibration of air molecules. The Pinna catches these air vibration and send these vibration to the middle ear through the ear tube.

=> The middle ear consists of the Three interlocked bones. The incus,malleus,stapes and the Ear drum. When the air vibrations travel through the eartube, the eartube takes these air vibrations and makes the eartube to vibrate with the same frequency and with the same amplitude, and this vibration of the eardrum causes the three interlocked bones vibrate.

=> The inner ear consists of the Hearing organ, auditory nerve and The sensory organ. The vibrations of the interlocked bones causes this hair like sturctures to vibrate. These vibrations are again caught by the Sensory organ and these sound waves are converted to mechanic waves and are sent to the auditory nerve by the hearing organ and then these mechanical waves are sent to the brain and the waves are again converted to sound waves and the brain understands these soundwaves and then we can hear the sounds.
