Homeostasis of the Ear

Homeostasis of the ear can be affected by deafness, disease and/or injury.

There are three types of deafness;
1. Conductive Hearing Loss: Ear wax, hearing infection, any fluid, calcium build up, or some other obstruction could be blocking the ear canal which interrupts the hearing process. This is only a mild form of hearing loss. Sounds may be interpreted as muffled or too loud.
2. Neural Hearing Loss: Also known as Nerve deafness. This occurs when the auditory nerve fails to carry the sound message to the brain to be interpreted. Sounds will sound too low or unclear.
3. Mixed Hearing Loss: Mixed Hearing Loss happens when two or more hearing defects occur at one time.

Diseases of the Ear include;
1. Otosclerosis: Is a hereditary disease that appears in the inner and middle ear. A type of bone sponge growth begins to develop. Once this reaches the inner ear it is undoubtedly permanent.

Injuries to the Ear include;
1. Eardrum Punctures: The ear drum could be puncture by foreign objects causing deafness/soreness. Car wrecks, sports, and big changes in air pressure could tear one's eardrum.
2. Nerve Damage: Damage to the ear nerves can result in permanent hearing loss. The sound will then not be transmitted to the brain to be interpreted.
3.Loud Sound/Noise: Long term exposure to loud sounds will result in some form of hearing loss. Only over a long period of exposure to loud sounds will increase one's chances of becoming mildly to severely deaf.
