Answer» Correct Answer - A The organ of Corti is a structure located on the basilar membrane which contains hair cells that act as auditory receptors.Movements of the basilar membrane bend the hair cells, pressing them against the techorial membrane.As a result, nerve impulses are generated in the associated afferent neurons.These impulses are transmitted by the afferent fibres via auditory nerves to the auditory cortex of the brain, where the impulses are analysed and the sound is recognised. |
