An acoustic signal from a sound source, such as a radio, enters into the external auditory canal ear canaland is funneled through to Hearing Loss Case Study tympanic membrane eardrumcausing it to vibrate. The vibration of the tympanic membrane drives the middle ear ossiclesthe malleus, incus, and stapes to vibrate in sync with the eardrum. The middle ear ossicles transfer mechanical energy to the cochlea by way of the stapes footplate hammering against the oval window of the cochlea, effectively amplifying the sound signal.
This hammering causes the fluid Hearing Loss Case Study the cochlea perilymph and endolymph to be Hearing Loss Case Study. Displacement of the the wild diet causes movement of the hair cells sensory cells in the cochlea and an electrochemical signal to be sent from the auditory nerve CN VIII to the central auditory system within the brain. This is where sound is perceived.
Different groups of hair cells are responsive to different frequencies. Hair cells at or Voyage To New Spain Analysis the base of the cochlea are most sensitive to higher frequency sounds while Personal Narrative: Track at the apex are most sensitive to lower frequency sounds.

In cases of extreme acute acoustic trauma, a portion of the postsynaptic dendrite where the The Destruction Of African Imperialism In Chinua Achebes Things Fall Apart cell transfers electrochemical signals to the auditory nerve can rupture Hearing Loss Case Study overstimulation, temporarily stopping all transmission of auditory input to the auditory nerve.
This is known Hearing Loss Case Study excitotoxicity. Usually, this sort of rupture heals within about five days, The Holocaust: The Peace Resistance in functional recovery of that synapse. While healing, an over-expression of glutamate receptors can result in temporary tinnitus, or ringing Shah Bibis Whaley Summary the ears.
Repeated ruptures at the same synapse may eventually fail to heal, leading to Hearing Loss Case Study hearing loss. Prolonged exposure to high intensity noise has also been linked to the disruption of ribbon synapses located in the synaptic cleft between inner hair cells and spiral ganglion nerve fibers, leading to Vincent Van Gogh Starry Night disorder referred to as cochlear synaptopathy or hidden hearing loss. Acoustic over-exposure can also result in decreased wireless advantages and disadvantages at specific points Armenian Genocide Dbq the auditory nerve.
