The inner ear has a sensory receptor inside the cochlea called the Organ of Corti. It is responsible for holding the hair cells, which are the nerve receptors for hearing. Movements of the middle ear bones create a mechanical energy that pushes on a membrane in the cochlea, causing the cochleaâs fluids to move.
The organ of Corti is located in the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells.he function of the organ of Corti is to transduce auditory signals and maximize the hair cellsâ extraction of sound energy. It is the auricle and middle ear that act as mechanical transformers and amplifiers so that the sound waves end up with amplitudes 22 times greater than when they entered the ear.
