ELI5: Explain Like I'm 5

Inner ear

The inner ear is like a tiny, squishy room inside your head that helps you hear and keep your balance.

Inside this room are three main parts: the cochlea, the semicircular canals, and the vestibule.

The cochlea looks like a snail shell and is responsible for sending signals to your brain that help you hear different sounds. It has tiny little hairs, like the bristles on a toothbrush, that move when sound waves come into your ear.

The semicircular canals are three tiny tubes that are filled with liquid. They help you keep your balance by telling your brain which way your head and body are moving.

The vestibule is another part of the inner ear that helps with balance. It is like a little pouch that has a special type of cell that can feel when your head is tilted.

All of these parts work together to help you hear and stay upright!
