Organ of Corti
Updates to Article Attributes
The organ of Corti, also known as spiral organ, is the receptor organ for hearing, located in the cochlea (housed inside the scalae mediae). It is a strip of sensory epithelium made of hair cells which act as the sensory receptors of the inner ear.
Function
This is a vulgarisation of the complex operation that occurs in 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 1.
Etymology
The organ was discovered in 1851 by Italian anatomist Alfonso Giamoco Gaspare Corti (1822-1876) 2.
