WebThe function of the organ of Corti is to convert ( transduce) sounds into electrical signals that can be transmitted to the brainstem through the auditory nerve. [2] 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. WebMar 24, 2024 · Hair cells are vestibular receptors located on sensory epithelia and surrounded by supporting cells. According to the different afferent synaptic terminals, human vestibular HCs can be further classified into two types: Type I HCs innervated by flask-shaped calyces and Type II HCs innervated by boutons ( Wersall, 1956 ).
