Final answer:
The auditory receptors are called hair cells located in the organ of Corti within the ear. When these hair-like projections, called stereocilia, bend in response to sound vibrations, nerve impulses are triggered and transmitted to the auditory nerve.
Step-by-step explanation:
The auditory receptors are called hair cells located in the organ of Corti within the ear. These specialized cells have hair-like projections called stereocilia that detect sound waves. When the stereocilia bend in response to sound vibrations, nerve impulses are triggered and transmitted to the auditory nerve.
