Quizplus · Accepted Answer

The correct route of auditory information from some external sound source to the auditory cortex in the brain is: eardrum – hammer, anvil, and stirrup – cochlea – hair cells – auditory nerve. This is because the sound waves first hit the eardrum, which starts the vibration of the small bones in the middle ear (hammer, anvil, and stirrup), leading to the movement of fluid in the cochlea. The movement of fluid in the cochlea stimulates the hair cells, which generate electrical signals that are sent to the auditory nerve and then to the brain for interpretation.
