Semicircular Canals

Protruding structures inside the ear, called the ampullae, contain sensory hair cells surrounded by endolymph fluid. As the body moves, the fluid within the ear moves as well. Due to inertia, however, the fluid moves more slowly than the body does. When we move very rapidly, there may be a small delay as the fluid “catches up” with the body.
