Quizplus · Accepted Answer

Bending the stereocilia, which are hair-like structures on the sensory cells of the inner ear, triggers nerve impulses that travel through the auditory nerve to the brain, where they are interpreted as sound. The ossicles (A) are small bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear. The stapes (C) is the smallest bone in the human body and is one of the three ossicles. The pinnas (D) are the visible parts of the ear that help collect sound waves and guide them into the ear canal.
