Cochlea

Living in Nashville, the music city, everybody’s life abounds with melodies. Although many people think music is an abstract art form that is devoid of clear-cut ideas, it never fails to touch us deeply, stimulating some universal nerves. When the prelude of our favorite song rings out, our whole bodies get prepared for that specific note. None of us would deny that music is biologically powerful. However, music’s precise influence on our brains and how we take advantage of its power deserve…

Medication, occasionally counting surgery, is required if the fissure creates complications. Temporal bone fractures induce numerous damages to the internal ear. Damages encompass burst of the eardrum and injury to the ossicles, the cochlea, the vestibular apparatus, or the nerve that regulate muscles of the visage. Occasionally, serous fluid taken away from the brain and spinal cord (cerebrospinal fluid) flows from the brain into the fracture and emerge as unclouded fluent depleting…

Chapter 10 • A. Why might Mr. Williams be having difficulty hearing his wife’s voice? Provide specific reasons and examples. (8) • Mr. Williams might have difficulty hearing his wife’s voice because he has a hearing loss most likely affecting his cochlea. Mr. Williams most like has presbycusis which is hearing loss from old age since he is 69 years old. Also, since he cannot he his wife when she is speaking he probably has a high frequency hearing loss which is a very common sign of…

performed on infants and detect sensory hearing loss. However, A-ABR test measures the peripheral auditory system, as well as the cranial nerve and brainstem pathway, while EOAE test measures the peripheral auditory system and the outer hair cells of the cochlea. In the past, NIH has recommended ABR testing for infants who failed initial EOAE testing (NIH, 1993). While infants with positive ABR results (hearing loss was suspected) would continue on to further audiological diagnostic testing.…

Conductive hearing loss occurs when there is a problem in the outer or middle ear, so sound cannot be conducted the same as in a healthy ear. Sensorineural hear loss is caused by non-functioning hair cells in the cochlea. Sensorineural is more serious because it could be permanent. Both sensorineural and conductive hearing loss limit the ear from producing the same sound as a healthy ear, but they are treated in different ways. Conductive hearing loss can be treated…

consolidate blood vessels, nerve cells, etc. with the printed organs. In addition, size remains a problem, whether the organ is large or small. At present, the technology cannot achieve the level of anatomical detail required for a working retina or cochlea, nor the complexity of an organ such as the heart or liver. However, bone and skin tissue have proven to be engineerable and has been successfully integrated into living human patients. Research is currently being conducted to print tissue…

I’m All Ears for Cochlears; Making Our Way to A Hearing World Imagine this, a world where people can't hear anything. Where people don't know what talking, music, or even the rustling of leaves sounds like. A deaf person lives in that world. Their world is silent. Most people get hearing loss once they grow older or are involved in some type of trauma, but what most people do not know is, “15% of children between the ages of 6-19 have a measurable hearing loss in at least one ear”…

The way we sense things is how we perceive the world around us, and to also make sense of it all. The sensory organs I chose to explain are the nose, tongue, and ears and how they connect to the brain for our perception. As we inhale the scent of something, the molecules reach the receptor cells high in both nasal cavities. Then the axons from millions of these receptors carry nerve impulses directly to the olfactory bulb. The olfactory bulb is the smell center of the brain. From there, records…

As I take you through the path of light I will be explaining what each structure is responsible for and how it handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the…
