The organ of Corti (or spiral organ) found only in mammals is part of the cochlea of the inner ear and is provided with hair cells or auditory sensory cells. It evolved from the basilar papilla found in all tetrapods except for a few derived species that have lost it.The organ was named after the Italian anatomist Marquis Alfonso Giacomo Gaspare Corti (1822–1876) who conducted microscopic research of the mammalian auditory system.
