A cochlear implant can restore hearing in individuals with damages to the cochlea. Research the functions of the following 4 parts of a cochlear implant (microphone, processor, transmitter, electrode array).

Describe the function of each structure of the implant and identify the structures with similar functions in the sound pathway below. (4 marks)

pinna → auditory canal → tympanum (eardrum) → ossicles → oval window → cochlea (organ of Corti) → auditory nerve → brain (temporal lobe)

Cochlear implant can be used to restore conduction deafness. The conduction deafness which is caused by the impairment of the middle ear can be caused by the failing of the device that cause direct stimulation to the hearing nerve to fail. The cochlear implants restore stimulation of the sensory nerve in the inner ear.

The microphone in the cochlear implant transmits the sound directly to the processor.

The processor in the cochlear nucleus captures and translates the sound in order to give a clear signal and enable the patient to access the missing sounds.

The transmitter receives the sound and converts it to electronic impulses

An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve

Thankyou! Can someone also identify the similar structures please

I believe the microphone would be the tympanum (eardrum).

Transmitter would be the bones ossicles.

The processor is the brain.

And, inside the cochlea, there exists what are known as hair cells. They'd be the electrode array

This is my guess
