What is an example of information

How does the sense of balance work?

Each of the semicircular canals opens into a bulge in which there are small sensory hairs. These bulges are also called ampoules. For example, when the head rotates, the inner ear rotates with it. However, it always takes a short moment for the fluid in the semicircular canals and the ampoules to take part in this rotating movement. The result: the hairs are bent over by the "sluggish" liquid. The hairs pass this stimulus on to the brain as a nerve signal.

Each of the three semicircular canals is responsible for a certain direction of movement of the head: one at a time registers when the head

  • tilted up or down,
  • tilted to the right or left or
  • is turned sideways.

The otolith organs are located diagonally under the semicircular canals and function in a similar way: Both sacs also contain fine sensory hairs. The difference to the semicircular canals: Small crystals adhere to the hair - like stones on a carpet. Experts call the crystals otoliths. Acceleration is perceived with the atrial sacs. For example, the feeling when you are driving in an elevator, falling, driving off or braking while driving a car.

The information from the equilibrium organ is processed in the brain and passed on to other organs that rely on this information, for example the eyes, joints or muscles. This allows us to keep our body in balance and orientate ourselves in space.

In certain situations, for example on a ship or in an airplane, contradicting information reaches the brain from various sensory organs, for example the eyes and the organ of equilibrium. This can lead to malaise, dizziness or nausea.

While the balance organ is particularly sensitive in children, it no longer reacts as quickly to movements with increasing age. In addition, problems such as infections in the inner ear can impair your sense of balance.
