E for Ear- Equilibrium and Sound Detector!!
I was cleaning my cupboard and out came a diagram of the Human Ear popping out from a corner. I had stored this small diagram for which I had taken pains to draw during my school days as a fond memory. Our body keeps fascinating me every day with the amount of work it does with fine precision.
So, when the letter 'E' popped in as the topic today, I chose ear which popped out of my cupboard.
Eye is an organ which has always been in the limelight when it comes to facial features.Eye displays immense detail and expressions which none of the digital devices could replicate. The ear at the sides is often neglected.Ear is only considered as an organ which detects sound but it's also the organ which maintains our body balance.Many non-science students are unaware of this fact. The legs and the spinal cord help us stand straight but the ears ensure that our balance is maintained.
What fascinates me the most is the anatomy of the ear and the parts involved in maintaining the equilibrium of our body. There are three semicircular canals (superior,posterior and horizontal) and ampulla which are involved in sustaining dynamic equilibrium while the utriculus and sacculus are involved in maintaining the static equilibrium. These parts of the inner ear are encased to the hardest bone in the body while the sound is redirected to our brain.
The speed at which all these happens is the most magical aspect of human hearing.The sound enters the human ear as waves with air as the medium.Inside the ears, the medium of sound is converted from air to liquid.Following, this the sound goes through the middle ear to reach the cerebral cortex of temporal lobe of the brain.Here depending, on the language spoken the deciphering of the information takes place which is interpreted by our brain.All these conversions keep happening dynamically with our ear tracking every possible sound within our vicinity and sending it to our brain. Doesn't this sound magical???
Some of the interesting facts about ears and hearing:
1> We can hear sounds better during rainy seasons.This is because when the moisture present in the air is more the time taken for air-liquid wave conversion mentioned above is minimal thereby increasing the clarity in hearing.It also increases our hearing radius.
2>When a loud jarring noise is heard or when water enters into our ears, the inner parts of our ear is affected thereby troubling our hearing.Especially during loud noise, our ears become paused for a moment and we get a strange compressed feeling in our ears.This is called as temporal masking.
3> A personal suggestion. Please limit your usage of earphones as it impairs hearing when used for longer duration.Naturally, air has to enter through our ears. While using earphones, digital noise enters into our ears and when nature is changed problems arise.When the disturbance is limited, it's always advisable to use earphones with less volumes.
Forgot!! For those piercing your outer ears, NO PROBLEMS! It's a great fashion statement.You can keep doing that :D
