Cochlea Research Paper

When a person with normal hearing hears the sound travels along the ear then bounces against the ear drum. The eardrum, the bones inside, and the cochlea vibrate and move thousands of tiny hairs inside the ear. When these hairs move an electrical response occurs. This electrical response goes to the hearing nerve and then it is send to the brain.

Basically how sound travels through the ear is a process of many steps. The sound waves are gathered by the pinna and then funneled into the meatus. Those waves then begin to vibrate the tympanic membrane which in turn hits against the malleus. The ossicle bones then vibrate like a chain reaction. The footplate will hit the oval window which triggers the fluid in the cochlea to move. The movement sways across the different hair cells creating impulses that are sent to the brain through the eighth cranial nerve.

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

The advent of new technologies such as the cochlear implant will not ultimately eradicate Deaf culture. The Deaf community is too close-knit to become torn apart. Not everyone has access to these new technologies because they are not eligible for them or the price is not right for their low budgets. Similarly, not everyone will be successful with the cochlear implant and most will return to Deaf culture for the rest of their lives. However, for those who are successful, they can still be a part of Deaf culture if they are bilingual and have adequate access to the Deaf community and its members. Knowledge is power and ASL education is spreading throughout high schools and universities all over the United States. These are several factors that

The middle ear has three ossicles (tiny bones) the hammer, the anvil, and the stirrup that connect the middle ear to the inner ear. When sound enters your middle ear, it causes the ossicles to vibrate. These vibrations then move into the cochlea, which is filled with fluid. When the vibrations move the fluid that is in the cochlea, it stimulates tiny hair cells that respond to different frequencies of sound. After the tiny hair cells are stimulated, they direct the frequencies of sound into the auditory nerve, as nerve impulses. (ASHA 2013)

Being able to hear is something I think most people take for granted. But what if you cannot hear? On July 15, 2015, I was afforded the opportunity to observe eight-year-old Braydon Smith and five-year-old Peyton Smith, who were born deaf. Their names were changed to protect their identity. Their younger sister, Mackenzie, whose name was also changed to protect her identity, did not have any issues with her hearing. I met with both boys and their mother, Sandra Smith, at a relative’s home in Belton, Texas. However, the family lives in Loganville, Georgia. I found both boys to be energetic, and playful. Their mother seemed excited to tell her sons’ stories. Present at the meeting was Sandra Smith,

Hi Amy. I have just wanted to expand on your post. In the beginning of chapter 10, Sacks explores medical history. He argues that the course taken by sound vibrations, from their entry into the external ear canals, through the eardrums on either side to the small bones, the ossicles, of the center ear, to the snail-molded cochlea, was initially worked out in the seventeenth century. It was believed then that sounds were transmitted by the ear, becoming enhanced in the cochlea "as in a musical instrument." After a century, it was found that the tapered shape of the cochlear spiral was differentially tuned to the scope of discernable frequencies, responsive to low sounds at its wide base, high sounds at its narrow apex. At last, by 1700, it was

After watching Kelly and analyzing the actual surgery of the cochlea implant, the inner ear and how we receive signals makes more sense. To be honest I had to watch this video multiple times and look up ways they perform the surgery to get a better overall understanding. However thinking about how we pick up noise and hear sound differs between each individual, such as light. It all depends on our hair cells, which

The ear is made up of three parts: the outer ear, the middle ear and the inner ear. The outer ear is responsible for collecting the sound wave, the middle ear increases the sound energy and transmits the sound to the inner ear and finally the inner ear transforms the sound waves into nerve impulses and sends them to the brain. When the sound wave passes the ear canal there is a vibration in the eardrum which affects 3

The cochlear implant is a incredible device that all started out in the 1950s, when "Lundberg performed one of the first recorded attempts to simulate the auditory nerve with a sinusoidal current during a neurosurgical operation"(MAJOR BREAKTHROUGHS! (n.d.). Retrieved April 25, 2015, from http://biomed.brown.edu/Courses/BI108/BI108_2001_Groups/Cochlear_Implants/history.html ). After the operation his patient was able to hear noise. This device as been changing peoples lives for a long time, with time it has improved. there are other things in this world that changed people lives, that benefits them, so

Different frequencies reach their peak at different positions along the tube, which allows the cochlea to distinguish them. Researchers have found that the spiral shape significantly enhances the “vibrational motions” that translate into nerve signals. However, if the cochlear is damaged it is obvious how important the development of the cochlear implant is. Essentially the cochlear implant serves as a bypass for damaged sections of the ear, replacing the function of the ineffective hair cells.

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected, absorbed, and also filtered by our different body parts. It's then collected by our pinnae (the external part of or ears), whose dimensions further affect the sound on its way into ear. There, vibrations are translated into signals, which are interpreted by your brain. In the 1930s, two scientists at Bell Labs, Harvey Fletcher and Wilden A. Munson researched this process and what they discovered has changed and affected how we as humans understand the hearing process.
