The organ of Corti is the receptor organ for hearing, located in the cochlea of inner ear. The organ of Corti consists of outer hair cells, inner hair cells, inner pillar cells, outer pillar cells, tunnel of Corti, phalangeal cells (cells of Deiters), 1 cells of Hensen and cells of Claudius. The sensory hairs project from the outer ends of the hair cells into the scala media, while from the inner end of the cells nerve fibres arise, which unite to form the cochlear nerve. The sound impulses received by hair cells of organ of Corti are carried to the brain through the auditory nerve where the sensation of hearing is felt. Thus organs of Corti function to respond to sound impulses.
