  • Topic: Ear.

  • How do ears help with balancing?

  • They really do.

  • You don't believe me.

  • Ok.

  • Can you play a guitar and walk at the same time?

  • How do you think you are able to maintain your balance?

  • Do you know why you can't balance yourself anymore?

  • Wait, I will tell you.

  • This happens because there is a connection between our ears and body balance.

  • Our ear consists of 3 parts, outer ear, middle ear and inner ear.

  • Our inner ear works in sync with our eyes and muscles.

  • Helping us maintain balance, while we are doing various activities.

  • The inner ear consists of three semicircular canals.

  • Called superior semicircular canal, posterior semicircular canal and lateral semicircular canal.

  • The three semicircular canals are arranged in three different positions.

  • Each of these canals has a fluid called endolymph and hair cells called cilia at the base.

  • Whenever we move our head, the fluid moves, resulting in the movement of the cilia as well.

  • When the cilia moves.

  • It sends signals to the brain informing which direction our head has just moved in.

  • Each canal has different functions as per the movement of our head.

  • When we move our head up and down.

  • The superior semicircular canal helps our brain to understand the yes motion.

  • When we tilt our head towards our shoulders.

  • The posterior semicircular canal helps our brain to understand the tilting motion.

  • When we move our head from side to side.

  • The lateral semicircular canal helps our brain to understand the no motion.

  • It was too complicated, right?

  • Ok, don't worry about it.

  • Relax.

  • Why don't you go on a merry go round ride?

  • Hey.

  • Why were you not able to maintain your balance?

  • This is because when you sat in the merry go round and started rotating.

  • The fluid in the semicircular canals also started to move.

  • After a while, it was moving at the same rate at which you were moving.

  • However, when the ride stopped and you got down from the ride.

  • The fluid was still in motion due to inertia.

  • Hence, even though you were not moving.

  • The moving fluid gave your brain false information telling that you are still in motion.

  • Thus, you were not able to maintain your balance.
