Consisted of the eardrum, three ossicles (malleus, incus and stapes) and the eustachian tube.

 

-

Eardrum vibrates and transmits sounds to the middle ear. Three ossicles then further magnify the vibrations and transmit them to the inner ear through the oval window.

  

-

The eustachian tube is the pressure equalizer. It helps to equalize pressure between the outer and middle ear. Eutachian tube dysfunction will lead to the sensation of ear blockage and perception of echo sound.

response to the movements of the three ossicles, the fluid and hair cells inside the cochlea are stimulated and moved. These movements are then converted into electric impulses, which then pass through the acoustic nerve to other relevant parts of the brain, enabling us to interpret the sounds.
