What is the job done by the semi-circulare canals?

The semi-circular canals are part of the inner ear and play a crucial role in maintaining balance and spatial orientation. They contain fluid and hair-like sensors that detect rotational movements of the head. When the head moves, the fluid within the canals shifts, stimulating the hair cells, which send signals to the brain to help coordinate balance and movement. This system is essential for activities that require precise balance, such as walking, running, and turning.
