Definition of organ of Corti in English:

organ of Corti


  • A structure in the cochlea of the inner ear which produces nerve impulses in response to sound vibrations.

    • ‘In man, the cochlea and the organ of Corti follow a spiral course of two and one half turns.’
    • ‘The micromechanics of the organ of Corti and the tectorial membrane is then analyzed by our new method.’
    • ‘A cochlear implant takes the place of the damaged organ of Corti and stimulates the spiral ganglion cells directly.’
    • ‘Standard theory states that cellular structures in the organ of Corti move in unison as a rigid body, around a hinge point located at the attachment of the basilar membrane to the bony core of the cochlea.’
    • ‘These data imply that structural relations within the organ of Corti were dynamically changing during sound stimulation, a fact that directly contradicts classical models of organ of Corti vibration.’


Late 19th century: named after Alfonso Corti (1822–76), Italian anatomist.
