Question

Explain outer, middle and Inner part of ear.
​

Answer 1

hey mate! outer ear- the part of the outer ear that is visible to us is called pinna. the pinna collects sound waves and directs them to the ear tube. at the end of the ear tube is the ear drum .the ear drum vibrates when sound waves strike it and transmit the vibration to the ear.
middle ear- the middle ear is a cavity with three important ear bone these three bone are placed in such way that they move when ear drum vibrates and transmit vibration to inner ear.
inner ear- the inner is connected to the middle ear through a small opening the inner ear is filled with a fluid when this fluid vibrates it excites tiny hair in inner ear these hair transform the vibration into electrical impulses which are then transferred to the brain via the auditory nerve this is how we hear a sound.
hope this help you out......

Answer 2

Pinna collect the sound from the surrounding . the sound reach the eardrum through ear canal to make it vibrate . the three bones (hammer ,anvil and stirrup present in the middle ear amplify this vibration and distribute the sound of different frequency .this amplifier vibration reached into the cochlea through semicircular canal. the fluid present in the cochlea contain hair nerves. which convert into the brain impulse the brain impulse goes into the brain through auditory nerve. the brain decodes the information and preceive the sound as it is.
