Standing, walking, and spinning all need balance. Your brain combines signals from your eyes, muscles, joints, and inner ear. The inner ear part is called the vestibular system. It lives deep in bone beside the cochlea you use for hearing. It tells the brain which way is up and how fast your head is moving. Without it, even flat ground would feel wobbly. Athletes, dancers, and cats all rely on this hidden gyroscope every second.

Astronauts practice balance on Earth because microgravity confuses the vestibular system until the brain relearns in space.
