Semicircular canals

The semicircular canals are three tiny, fluid-filled structures located in the inner ear. They play a crucial role in our sense of balance and spatial orientation. Each canal is oriented in a different direction—horizontal, vertical, and diagonal—allowing the brain to detect head movements in all possible directions. When you move your head, the fluid inside these canals shifts, stimulating tiny hair cells that send signals to the brain. This helps you maintain balance and keep your body oriented, especially during activities like walking, turning, or tilting your head.
