nahz..nothing to do with tat..look at heavenscloud ans for clue...Originally posted by ndmmxiaomayi:Difference in pressure? Like atmospheric pressure? Not quite sure, read in a book. -
That is the cause for hearing and at times loss of balance... my question is why is there a loss in balance from these causes...Originally posted by ndmmxiaomayi:Difference in pressure? Like atmospheric pressure? Not quite sure, read in a book. -
We studied nothing about ears for bio because syllabus changed.Originally posted by alfagal:nahz..nothing to do with tat..look at heavenscloud ans for clue...
Do some research first. Post the answer in a while. -
very complicated to type out the whole thing lehz.Originally posted by renorenal:well... wat bout the cochlea?
basically, there's this certain system inside (i think) the cochlea.
the functioning of this system depends on information from many systems, hearing as well as vision and muscle feedback.
so when u cant hear, this system malfunctions.
dunno im right or not. -
close, jus name tat exact spot tat is responsible for all these happenings...

no need the whole thing one lar... haha... keep things simple man... i know u are thinking of the complicated nerve fibers travelling from the peripheries (of the joints, the visual, the auditory .etc) to the cortex thingy, but that's not what I'm concerned of...Originally posted by heavenscloud:very complicated to type out the whole thing lehz.

Why is the funny bone called a funny bone? [/b] -
Found out about how the ears work, but cannot link back to your question.
Sound waves are first collected in our outer ear (called the auricle or pinna), pass through our ear canal and cause our eardrum to vibrate. These vibrations are in turn transmitted to our inner ear by the bones of our middle ear. Our inner ear plays a vital role in the transformation of these mechanical vibrations into electrical impulses, or signals, which can be recognized and decoded by our brain. When the vibrations reach the cochlea through movement of the bones in the middle ear, the fluid within it begins to move, resulting in back and forth motion of tiny hairs (sensory receptors) lining the cochlea. This motion results in the hair cells sending a signal along the auditory nerve to the brain. Our brain receives these impulses in its hearing centers and interprets them as a type of sound.
Not quite sure, but I think is this:
Due to the difference in pressure, it causes changes in the fluid within the middle ear. The changes in fluid probably cause the giddiness in us. -
how i know the FFF response arh?Originally posted by renorenal:and what is that activity called? -
