Turn down that music and listen up! Your ear is a remarkable sensory organ with three parts: the outer ear, the middle ear with the eardrum, and the inner ear. The inner ear is a bony labyrinth that creates our sense of balance and hearing. Balance is controlled by three semicircular canals containing fluid and tiny hairs. When you tilt your head, the fluid adjusts and pushes the hairs, sending nerve signals to your brain so you can make balance corrections. The cochlea is the main organ of hearing. This snail-shaped bony casing converts mechanical sound vibrations into electronic nerve signals. It contains the basilar membrane and an intricate collection of hair-like nerve filaments, called hair cells. The membrane vibrates in response to sound. Thousands of these hair cells respond to different sound pitches based on their location on the membrane. High pitched sounds impact the base of the cochlea where the membrane is more narrow and thick. Low pitched sounds stimulate the inner tip where the membrane is wider and flexible. Thus, sound vibrations become electronic signals that travel from your auditory nerve to your brain which processes and interprets the sound.
