The ear is made up of the inner ear Middle ear Inner ear
The outer ear is the part of the ear that sticks out from the sides of your head. It is shaped in such a way to effectively collect sound waves. The sound waves travel through a short tube and reach the ear drum. The ear drum is a thin membrane that separates the outer ear from the inner ear.
On the other side of the ear drum is the inner ear. The inner ear has three tiny bones. When sound waves causes the ear drum to vibrate it causes the tiny bones to vibrate as well and this passes on the vibration to the inner ear.
The inner ear has a structure called the cochlea. The cochlea contains a fluid and many tiny hairs. The vibrations passed on from the middle ear cause the fluid and hairs to move. The tiny hairs are attached to nerves that convert the vibrations to nerve signals that the brain interprets as sound.
HOW YOUR EARS HELP TO GIVE YOU BALANCE
The fluid and tiny hairs in the inner helps the brain to figure out in which direction is head is located. This helps it to coordinate muscles to help us keep balance. This is why when you spin around a number of times you become dizzy as the fluid in the inner ear is disturbed.
