Introduction - Role of the Ear in Maintaining the Body Balance

Have you ever noticed what happens when you spin around for a minute? You cannot stand firmly, right? Why does spinning make us feel dizzy? All of the above happens because of our ears and the fluid-filled inside them. Ear is our sense organ that helps us in hearing. There are different parts of the ear like the outer ear, middle ear, and inner ear. It is because of the fluid and related ear mechanism we can stand firm. This fluid is endolymph which is filled in semicircular canals. As a result, our ear plays a significant role in balancing our bodies and keeps us static. But, the question is how?

So, in this article, you will learn all about balance in the ear and how the ear balances the body.

What is Ear?

The ear is the organ that creates our sense of hearing and balance. Also called the sense organ of hearing. This organ is in charge of capturing sounds around us and sending signals to the brain so we can react accordingly.

For example, imagine hearing the siren of an ambulance. Your ear collects the vibrations from the siren and signals your brain for you to move out of the way of the ambulance.

What is Ear Balance?

The balance, which is maintained and regulated by the help of our ears and their related structures, is called the balance in the ear. The part of the inner ear is responsible for this. Medication, ear infections, and head injuries can cause ear balance problems.

Structure or Anatomy of the Ear

The ear is divided into three parts: the outer ear, the middle ear, and the inner ear.

The Outer Ear

The outer ear is made up of two parts: The Oracle and the Auditory canal.

The Oracle or the ear lobe/pinna - It is the part of the ear that captures sound waves. The auditory canal is the part of the ear through which sound travels to reach the middle ear. The outer ear also has some hair and wax-producing glands that help the ear to be clean and guard it against harmful bacterial attacks.

The Middle Ear

The middle ear comprises the eardrum and three small bones: the hammer, the incus, and the stapes. They transmit sound to the cochlea. A tube (named Eustachian tube) is also located in the middle ear. This tube connects the middle ear to the throat. The primary function of this is to equalise the pressure within the ears so that the eardrum can correctly translate sound vibrations to the auditory nerves.

The eardrum is a membrane similar to a drum head located between the outer and inner ear. When sounds reach in tympanic tissue, it vibrates and causes the tiny bones to move. Next, the tiny bone called the hammer, incus, and stapes start moving and raise the vibration transmitted by the ear drum, then the bones send the amplified signal to the cochlea.

The Inner Ear

The cochlea is located in the inner ear and is a structure of elastic which is usually coiled and looks like a snail shell. This part of the ear is in charge of converting the vibration received by the middle year into a nerve signal to send it to the brain through auditory nerves.

Along with the cochlea are connected the semicircular canals, which are usually three tiny tubes that are interconnected, and their job is to help to maintain the body's balance. The semicircular Canals are filled with fluid that is the essential liquid in the ear for balance.

The Main Balancing Portion: The Semicircular Canals

The semicircular canals are filled with fluid, and their walls are lined with tiny hair. When we move our heads, the fluid in the canal moves around and reaches the hair. The hair sends our position information as a signal through nerves to our Brain. The brain interprets those signals and messages towards the muscle and helps us stay balanced.

The movement of the fluid of the semicircular canal is the sole reason behind the dizziness we feel after spinning around. When we spin around and stop, we feel dizzy because the fluid in our semicircular canal also sloshes around, again and again, giving our brain the idea that we are still spinning when we have stopped; when the fluid stops moving, the dizziness goes away.

Fluid in Ear Balance

The fluid in ear balance that helps us maintain our balance is called endolymph, which is usually filled in the ear's semicircular canals. Another liquid in the ear for balance is the perilymph. The whole semicircular canal is filled with endolymph and floats in the perilymph. Both these fluids work together and maintain our body balance.


The ear is the sense organ that aids in hearing. The ear is also helping in maintaining balance which is known as ear balance. Ear balance is an essential mechanism for humans to stand still and maintain balance, which is regulated by the fluid filled inside the semicircular canals known as endolymph. If there is fluid imbalance because of injury or infection, ear balance gets disturbed. Dizziness occurs because of this fluid if disturbed.

In this article, we discussed the anatomy of the ear and its parts outer ear, middle ear, and inner ear and their respective parts and functions. We hope we were able to clarify all the concepts and queries regarding balance in the ear.

FAQs on Role of the Ear in Maintaining the Body Balance

1. What structures in our body help us maintain our balance?

The cerebellum part of the brain, also called the miniature brain, performs various essential functions, but one of the most important is maintaining balance. Along with the cerebellum, our ears also participate in maintaining body balance.

2. Can we prevent ear balance?

Ear balance is a natural mechanism that happens every time the fluid in our ear splashes and signals our brain. But yes, ear balance can be prevented to some extent through various techniques. Many sports involve techniques where the player has to spin around a lot, leading to ear balance and can cause disbalance in their performance. Therefore, those players are trained in balance retraining exercises, diet, and lifestyle changes. 

3. Do eyes and vision also play a role in balance?

Yes, our vision can play a significant 20 percent role in balancing our body as our eyes are heavily supplied by various nerves that directly impact and signal the brain, which impacts our balance and movement. 

4. If someone has hearing loss, can that affect their balance?

There is no scientific result or support for the fact that hearing loss can affect our balance. Hearing can be affected by various underlying causes, but the presence of a semicircular canal is what maintains the balance. Therefore, if one has healthy semicircular canals, their balance will not be affected.
