1. When a sound enters the ear, what are the structures it passes through on its way to become a fully processed neural signal within the brain? Fill in the blanks below. Sound enters through the pinna Lof the ear, which funnels it into the External auditory meatus At the end of this structure is the ear drum which vibrates because of the pressure waves created by the sound. This vibration causes movement in a series of bones: first, a small bone called the malleus; second, a small bone called the incus; and third, a bone called the stapes, which is connected to the of the inner ear. The movement of these bones causes fluid within the cochlea to move, resulting in movement of the membrane. The movement of this membrane causes the to move against the. membrane, resulting in the creation of a neural signal. This signal travels through the nerve, which is transferned to the nucleus of the in the brainstem. From there, information is relayed through multiple regions in the brain, eventually reaching the of the cerebral cortex.
