Interesting Human Ear Facts: 1-10
1. Let us begin with something that everyone understands. Ears are organs designated for hearing. But, did you understand that there is a limit till which ears will act properly. The minute a sound surpasses the natural hearing limit, our ears will buzz! How about asking your good friend to shout at his or her highest possible volume right into your ears? The outcome will be buzzzzzzzzzzzzz... 2. Did you know that our ear has 3 bones which are so small that they can be positioned together on a cent? These three bones are called stapes, malleus and incus. Expensive names, huh? Well, the first fellow, i.e. stapes is the smallest of these three bones.
3. Wan na go merry-go-round for a few days? Merely damage your inner ear and voila, objective accomplished! On a severe note though, 'merry-go-round' in this context indicates losing your body's equilibrium. Inner ear has direct connection with brain and anything occurs to the inner ear suggests ... you get it right?
4. Ever wondered why whenever you capture cold, you go dumb? I mean, you lose your voice! That's because middle ear is connected to the throat utilizing a tube called Eustachian tube. This tube is responsible for striking stability between the body pressure and the air pressure.
5. We just discussed inner ear and middle ear. This just suggests that human ear is divided into 3 parts-- the outer ear, the middle ear and the inner ear. Each part has separate functions. The external ear is the noticeable part of the ear and its function is to direct the noise additional inside. The external ear ends where the eardrum begins.
6. The location after the eardrum is the middle ear which ends at what is known as oval window. This middle ear consists of the three tiny bones we mentioned previously. The sound that goes into the outer ear makes the eardrum vibrate. These vibrations are gotten by these 3 bones which actually form a bridge. The last bone is the stapes (in order of plan inside the ear). The stapes transmits the vibrations to the oval window. The middle ear is the place where the noise gets enhanced.
7. Lastly comes the inner ear. The sound transmitted to the oval window moves into the inner ear which is in fact a network of passages and tubes. This network is often described as 'labyrinth'. This inner ear has a little snail shell-like organ referred to as cochlea where the noise is transformed into electrical impulses. These impulses are then sent out to brain's auditory center using auditory nerves and voila! We can hear!
8. In inner ear, the sound waves moves into a liquid medium. The small hair cells present in inner ear respond to the sound waves taking a trip through the liquid medium. This triggers the hair cells to release chemicals that are carried by auditory nerves to the brain.
Now, the entire thing is extremely complicated and if you want learning the entire thing in details, consider visiting this site.
9. Did you know why we get strange sensations in ear or perhaps go somewhat deaf when we go high up on mountains? That's since the Eustachian tube cannot preserve pressure resulting in lightheadedness, pain, ear pain etc.
10. Human ear functions even when a person sleeps. The ears will remain to pick up sound but brain blocks them out.
11. Human ears are self-cleaning organs. They produce what is called ear wax. Clinically, ear wax is referred to as cerumen which is produced by tiny pores present in ear canal. There are tiny hairs in ear canal which are called cilia. Cilia are responsible pushing the wax out.
12. Too much of anything is bad. So, too much wax is bad either! Too much of ear wax presses against eardrum and harms hearing abilities.
13. Did you know that ear wax, though disgusting, is very important since it safeguards the ear from dust and friction. Regularly cleaning ear wax can lead to deafness by destructive tympanic membrane.
14. Did you understand that American Indians and Asians normally have flaky and dry ear wax whereas Africans and Caucasians have moist brown wax? Also, ear wax has actually been used by anthropologists to study early migratory patter of mankind!
15. In ancient China it was thought that long earlobes signify long life while thick earlobes symbolize wealth. Not surprising that we see long ears of Buddha and in pictures of ancient Chinese emperors. It is thought that Liu Bei, the founder of small Han Dynasty in ADVERTISEMENT 221 had years so long that they reached his shoulders and he can seeing his own ears merely by glancing back!
16. There are 2 types of earlobes-- free and attached. Free earlobe is a variant where the lobe hangs freely from the head while the attached variation is signed up with to the head. Free version is twice as typical in people as the attached variation.
17. Ear piercing existed back in ancient times. Ötzi-- The Ice Mummy had both his ears pierced.
18. It was commonly believed among sailors that piercing one ear will enhance their vision.

20. Human beings can hearing sounds as low as 20 Hz. and as high as 20,000 Hz.
