Write down mechanism of hearing

1.	Write down mechanism of hearing
Answer» \tThe pinna receives sound waves and directs them to the ear drum.\tThe ear drum vibrates, and the vibrations are sent to the ear ossicles in the middle ear.\tThe ear ossicles further transmit the vibrations to the oval window.\tThe oval window passes the vibrations to the fluid of cochlea and causes vibrations in it.\tThe vibrations induce a ripple in the basilar membrane which bends the hair cells, which are pressed against the tectorial membrane.\tThis causes the generation of the nerve impulse which is transmitted to the brain via the auditory nerve.\tThe impulses are analysed, and the sound is recognised or heard.
