The vestibular system is a vital part of our body that helps us to maintain balance and coordination. It is located in the inner ear and is responsible for sensing changes in head movement and position.

​

The vestibular system is made up of three main components: the vestibular nerve, the vestibular nuclei, and the vestibular organs. The vestibular nerve carries signals from the vestibular organs to the brain, where they are processed and interpreted. The vestibular nuclei are located in the brainstem and are responsible for coordinating the signals sent by the vestibular nerve. The vestibular organs are located in the inner ear and consist of the utricle, saccule, and three semicircular canals.

​

The utricle and saccule are responsible for sensing linear acceleration, such as when we are moving forward or backward. The semicircular canals are responsible for sensing angular acceleration, such as when we are turning our head. Together, these three organs work together to provide us with a sense of balance and spatial orientation.

​

The vestibular system also plays a crucial role in maintaining our equilibrium. When we move, the vestibular organs send signals to the brain, which then sends commands to the muscles to make adjustments to keep us from falling. This is why we feel dizzy or disoriented when the vestibular system is not working properly.

​

Some common disorders that can affect the vestibular system include Meniere's disease, vestibular neuritis, and benign paroxysmal positional vertigo (BPPV). These disorders can cause symptoms such as dizziness, vertigo, and nausea.

​

If you experience any of these symptoms, it is important to see an audiologist to determine the cause and to receive proper treatment. Treatment options may include vestibular rehabilitation therapy, medication, or surgery.
