Ear stones and hair keep your balance

Your internal ear is covered in 3,500 microscopic hairs that detect even your slightest of motions.

Agood sense of balance is not located in your body, but in your ear. The vestibular sense makes sure that you can remain on your feet without getting dizzy, every time you move your head. The sense is regulated by a sophisticated system of hair, crystals, etc. in the internal ear.

When you look to both sides before crossing the street, a liquid moves in the internal ear, bending small, ultra-sensitive hairs, which are linked with the acoustic nerve. The nerve sends signals to the brain, which compares the information to sensory impressions from the eyes and neck, etc., to estimate whether it is only your head which is moving, or whether you have lost your sense of balance and are about to fall.
