Cochlea

In this paper, ototoxicity and its effects on hearing and balance will be discussed. Ototoxic drugs can affect different areas of the ear. It can affect anyone no matter the age, race, or gender. Although it is a common cause of hearing loss and balance problems, ototoxicity was not brought to awareness until the 1940s. Two common drugs that are damaging to one’s hearing are medications in the aminoglycoside family and cisplatin. There may be ways of preventing ototoxicity, but in some…

travel through the ear canal into the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to the malleus, incus, and stapes (three tiny bones in the middle ear). Once in the middle ear the vibrations are sent to the cochlea of the inner ear, which is filled with fluid. The vibrations…

Problem Set 7.1 a) Null Hypothesis: Within the 95% confidence interval there is no significant difference between the two-point threshold test disdances among the different areas. Alternate Hypothesis: Within the 95% confidence interval there is a significant difference between the two-point threshold test disdances among the different areas. b) The null hypothesis should be rejected because the p-value is 0 which is lower than 0.05, also because the conifence intervals for the back of the hand…

Hearing Impairment Student’s Name Institutional Affiliation Hearing Impairment Hearing impairment means loss of all or part of hearing ability due to sound signals not reaching the brain. Loss of hearing may be gradual or sudden depending on the causes. This condition is best described with reference to the affected part of the hearing system. The three basic types are conductive hearing, sensorineural hearing, and mixed hearing loss. Each of these losses has different causes. Conductive…

anatomy consists of the Outer Ear (pinna, ear canal, & ear drum) Middle Ear (ossicles-malleus, incus, & stapes) Inner Ear (cochlea, auditory nerve, & brain). With normal hearing the sound waves enter the ear canal which makes the ear drum vibrate. This action makes those tiny little bones in the middle ear move. Once the sound waves reach the last bone it then knocks on the cochlea. The fluid movement then triggers a response to the auditory nerve to the brain. Someone without normal…

Aim - The aim of this experiment is to find out at what age the ability to hear high frequencies begin to degrade. Hypothesis - As people get older the ability to hear high frequencies is much lower than the ability to hear high frequencies as a child. Background - As people get older, their capability to hear degrades whereas younger people like children, have a much better hearing since adults have experienced loud noises throughout their lives which degrades their hearing a little. The…

The special senses are hearing, equilibrium, vision, taste, and smell. Hearing is associated with the ear and how the sound waves travel through from external to internal ear. The external layer of the ear consists of the auricle, external acoustic meatus, and the tympanic membrane. Sound enters through the auricle, which carries the sound waves to the external acoustic meatus (i.e. ear canal). The external acoustic meatus in turn carries the sound waves to the tympanic membrane (i.e. eardrum).…

without facing some sort of detrimental repercussion. As hearing loss begin to run its natural course with Beethoven, he handled each stage with immaculate grace. Favoring to the low frequencies while those hair cells on the further end away from his cochlea while she still could. As he lost his hearing completely, compensatory and neuroplasticity stepped in, and Beethoven was still able to shine and write breathtaking compositions. He adapted by relying on what he knew his whole life, the…

conduction and sensorineural hearing loss in the right ear. Conductive hearing loss is due to damage to the eardrum (tympanic membrane) or bones (ossicles) in the middle ear, which prevents the sound from reaching the cochlea, and sensorineural hearing loss is due to damage to the cochlea or the cochlear nerve; thus, there may be damage to the subject’s middle and inner…

These types of losses are naturally not as severe as the sensori neural and can often be improved with hearing aids or surgery (-). A sensori neural hearing loss strikes in the inner ear, which involves impairment to the hair cells with in the cochlea or nerve endings. Noises are not heard because of this, or they are…
