The organ of Corti is the sensitive element in the inner ear and can be thought of as the body's microphone. It is situated on the basilar membrane in one of the three compartments of the Cochlea. It contains four rows of hair cells which protrude from its surface.he sensitive hair cells of the organ of Corti may have about 100 tiny stereocilia which in the resting state are leaning on each other in a conical bundle. In response to the pressure variations in the Cochlea produced by sound, the stereocilia may dance about wildly and send electrical impulses to the brain.
