Organ of Corti

The organ of Corti, also known as spiral organ, is the receptor organ for hearing, located in the cochlea.

Function

This is a vulgarisation of the complex function of the organ of Corti.

Transduction signals occur either through the vibration of structures in the inner ear (air conduction) or through vibration of the skull (bone conduction), causing displacement of cochlear fluid and movement of hair cells in the organ of Corti, which in turn produces electrochemical signals that release the neurotransmitter glutamate and then signals the auditory nerve.

Etymology

The organ was discovered in 1851 by Italian anatomist Alfonso Giamoco Gaspare Corti (1822-1876).
