Verified step by step guidance

Understand the anatomy of the ear: The ear is divided into three main parts - the outer ear, the middle ear, and the inner ear. Each part plays a role in the process of hearing.

Identify the function of each part: The outer ear collects sound waves and directs them to the tympanic membrane (eardrum). The middle ear contains the ossicles (malleus, incus, and stapes) that amplify the sound vibrations. The inner ear contains the cochlea and semicircular canals.

Focus on the cochlea: The cochlea is a spiral-shaped organ in the inner ear that is filled with fluid and lined with hair cells. It is responsible for converting sound vibrations into neural signals.

Explain the conversion process: When sound vibrations reach the cochlea, they cause the fluid inside to move. This movement bends the hair cells, which then generate electrical signals.

Connect to the brain: The electrical signals generated by the hair cells in the cochlea are transmitted via the auditory nerve to the brain, where they are interpreted as sound.
