Cochlea

Generic deafness can be classified into two sections syndromic and nonsyndromic. Nonsyndromic affects the ear only and consists of 43 genes that hold recessive mutations and 25 genes, which consist of dominant mutations. The restoration of deafness requires the introduction of a missing exogenous gene or gene product. Gene therapy offers the possibility of regenerating damaged cells by reprogramming cells to obtain the characteristics of the damaged hair cells. Researchers have discovered a gene

(last bone in the chain) causes the round window to move. The fourth flash video models the transfer of the mechanical energy into hydraulic energy within the cochlea as the round window vibrates with the stapes (from the Ossicular Chain).

What is deafness? Deafness is very different to people’s general perception of what it actually is. The most common view is that it is a complete loss of hearing however deafness is defined as the lack or loss of the ability to hear. You can either be born deaf or gradually lose the ability to hear later on in life (Presbycusis). Pre natal or congenital causes of deafness may be due to a specific X chromosome being passed on through generations of families even though there may be no previous history

sound waves into neural signals and also contains the cochlea. There are other things in the ear besides these three divisions such as the organ of corti which contains the cells responsible for the hearing hair cells. There are two types of these hair cells in the ear: inner and outer hair cells. Both of these cells work within the cochlea and have a stereocilia, an organelle of hair cells, but the outer hair cells function specifically in the cochlea. The outer hair cells contain the stereocilia at

A cochlear implant consists of an internal and external component. The internal component is surgically inserted under the skin behind the ear, and a narrow wire is threaded into the inner ear. Unlike hearing aids, cochlear implants convert sound waves to electrical impulses and transmit them to the inner ear, providing people with the ability to hear sounds and potentially better understand speech without reading lips. Speech and language ability varies among individuals, with many cochlear implant

the fluid inside the cochlea. This results in a change in pressure of the basilar membrane, moving the hair cells, which send information through the auditory nerve to the brain. A conductive hearing loss is when sounds are not conducted

Please answer these questions as thoroughly as you possibly can. 1. Please describe presbycusis of the cochlea giving the types and the anatomical site effect and the implications. Presbycusis is an acquired hearing loss associated with aging. There are four types of presbycusis: sensory presbycusis, neural presbycusis, metabolic presbycusis, and mechanical presbycusis. Sensory presbycusis occurs as a result of damage to the outer hair cells and inner hair cells of the organ of Corti. More damage

device that restores hearing for people anywhere from hard of hearing to the profoundly deaf. The cochlear implant is surgically implanted under the skin behind the ear. The surgeon puts the electrode array inside the inner ear and than inside the cochlea. The implant works by a device outside the ear, which rests on the skin behind the ear. It is held upright by a magnet and is also connected by a lead to a sound professor.      What happens when you get a cochlear implant

If the ear drum and middle ear are functioning properly, patients may benefit from a cochlear implant - a thin electrode is inserted in the cochlea, it stimulates electricity through a tiny microprocessor which is placed under behind the ear, under the skin. 3) Mixed hearing loss. This is a combination of conductive and sensorineural hearing loss. Long-term ear infections can damage both the

diseases such as rubella (German measles) or mumps may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When
