The semicircular canal is a part of the vestibular system in the inner ear and is essential for our sense of balance. Each canal is oriented in a different plane and filled with fluid. When we move our head, the fluid in the canals moves as well, stimulating specialized hair cells that send signals to the brain about the direction and speed of the head movement. This information allows us to maintain our balance, adjust our posture, and coordinate our movements effectively.
