Hearing, drawing

Illustration of hearing, journey of the sound wave in the ear. The sound wave is captured by the auricle, penetrates auditory canal, vibrates eardrum membrane, which in turn vibrates ossicles, malleus, incus, stapes). The vibration of the stapes make the fenestra vestibuli membrane vibrate which causes hydraulic waves in cochlea perilympha, blue), applying pressure on the endolymph inside the cochlea channel, moving the basilar membrane, pink), causing hair cells to move against tectorial membrane, producing a nerve impulse in the cochlea nerve fibers, yellow). This nerve impulse moves to the auditory nerve and carries the message to the auditory area of the brain, which analyses the data and enables us to hear the sound. Wearing headphones for a prolonged amount of time, at too high a volume, can damage the hair cells irreversibly. (Photo by: BSIP/Universal Images Group via Getty Images)
