A Hearing Center Adventure - Explorations of the Ear Health Articles | August 9 Craig Anderson Womens Jersey , 2012
Have you ever considered how many tiny parts need to work together in order for you to hear a single sound? At a hearing center, you'll explore charts and information on how your ear works, and how you can hear better.
If you've ever visited a hearing center, you've probably seen scores of different charts featuring the various parts of the ear. Have you ever wondered how all those little parts are used to allow sounds from the outside to be interpreted by your intelligent brain on the inside?
The Parts of the Ear
The ear is an amazing and complicated organ. It allows us to experience the world through the sounds that we hear every day. Waking up to the singing of birds, hearing the noise of city traffic as we drive to work Ryan Dzingel Womens Jersey , listening to our boss lay out plans for a new project during the morning meeting, and communicating with coworkers as we pass in the hall. All these everyday activities would be impossible if it weren't for our ears.
Three major sections comprise the ear - the outer ear, the middle ear, and the inner ear.
We see most of the outer ear. The part that we can see on the side of our head is known as the pinna or auricle in technical medical terminology. The ear canal connects the pinna to the eardrum. These three (pinna, ear canal Nate Thompson Womens Jersey , and eardrum) are the three main parts of the outer ear.
The middle ear contains three tiny bones - the malleus, the incus, and the stapes. Those of us who aren't medically inclined may also refer to them as the hammer, the anvil, and the stirrup Zack Smith Womens Jersey , for these are the shapes they resemble!
Finally, the inner ear, also known as the cochlea, is the primary hearing part of the ear. You may see a detailed chart of the cochlea when you visit the hearing center. It is filled with fluid and covered with small hairs called cilia.
So, What Do These Parts Do?
The outer ear's shape and size is perfect for collecting sounds. As you've probably experienced Tom Pyatt Womens Jersey , when you cup your hand around the back of the ear (extending its size), you'll notice that you can hear sounds even more loudly! So, the sound is collected by the pinna, travels down the ear canal, and hits the eardrum. As the eardrum vibrates Bobby Ryan Womens Jersey , it turns those sound waves to energy.
The bones of the middle ear also vibrate in response to the movement of the eardrum. When the oval "window" of the stapes (or the stirrup) vibrates, it causes the fluid in the inner ear to ripple - now the vibrations have traveled to the inner ear.
The ripples within the inner ear (or cochlea) fluid bend the microscopic hairs. These hairs (also known as the cilia) provide the final step in hearing. As they vibrate, they stimulate the auditory nerve. These nerve impulses are then passed to the brain where they are translated into the sounds that we recognize.
When Hearing Issues Arise
The doctors at a hearing center have taken years to study the intricate workings of the ear and all its amazing parts. Their goal is to assist those who are experiencing hearing loss - finding the problem and offering solutions.

SEOUL, March 31 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) declared a no-navigation zone in waters near the western maritime border Monday, indicating another missile launches Kyle Turris Womens Jersey , according to South Korea's Defense Ministry.
The DPRK issued the warning, which bans ships from sailing near the Northern Limit Line, or the disputed sea border, hinting that it will conduct firing exercises with rocket-propelled artillery guns near the tense maritime border.
Army Col. Wi Wong-seop, vice spokesman at the South Korean Defense Ministry Chris Wideman Womens Jersey , told a routine press briefing that Pyongyang informed Seoul of its shooting exercise plan, saying such notice was believed to have an intention of raising tensions on the Korean Peninsula.
The spokesman said the South Korean military has thoroughly prepared for possible provocations while operating emergency management teams to brace for possible incidents.
Pyongyang had not issued such warnings when they launched short- and medium-range missiles in recent weeks, causing strong backlashes from neighboring countries for its violation of the international maritime law.
On March 4 when the DPRK fired projectiles from its newly developed multiple-rocket launcher, one passenger jet was flying near the trajectory of the rockets at roughly the same time.
A China Southern Airlines jet with more than 200 passengers on board was heading for Shenyang from Tokyo when it passed through the same sky off the eastern coast of the DPRK as the trajectory of one of the shells.
South Korean Defense Minister Kim Kwan-jin cautioned last December that DPRK provocations would be highly likely between late January and March this year following the purge and execution of Jang Song-Thaek, once-powerful uncle of top DPRK leader Kim Jong Un.
The spokesman said that the DPRK's bellicose rhetoric and military threats tended to be focused on the timeframe Minister Kim mentioned Dion Phaneuf Womens Jersey , noting that during the period, South Korea and the United States are engaged in their annual war games.
The "Key Resolve" command post exercise, which began on Feb. 24, ended on March 6, but the "Foal Eagle" field training exercise will last until April 18 despite the DPRK's earlier call for delay or cancellation of the drills Mike Condon Womens Jersey , which Pyongyang has denounced as the rehearsal for a northward invasion.
