Understanding the Inner Ear: Function & Key Components

The inner ear is a delicate and complicated structure that includes the cochlea and vestibular system, both of which are a part of the labyrinth. Each part of the labyrinth performs specific functions, affecting hearing and more.

Cochlea

• The cochlea is the most well-known part of the inner ear. The cochlea contains different fluids that interpret incoming sounds as brain waves and transfer them from the ear to the brain. If these fluids mix, however, due to an inner ear rupture, hearing may be distorted or even lost entirely.

Vestibular System

• The vestibular system transfers data about head position to the brain. A disturbance in this part of the inner ear affects equilibrium, sometimes resulting in dizziness. The vestibular system affects balance and posture.

Labyrinth

• The labyrinth is a group of canals full of fluid. It connects the various parts of the inner ear and carries signals produced by the cochlea and vestibular system to the brain.
