Curved tubular canals in the inner ear that are concerned with equilibrium.
Any of three bony, fluid-filled loops in the osseous labyrinth of the inner ear, concerned with the sense and maintenance of balance.
Half-circle-shaped structures within the bony labyrinth of the inner ear that are critical to maintaining balance.
Three tubes that form part of the membranous labyrinth of the ear. They are concerned with balance and each canal registers movement in a different plane. At the base of each canal is a small swelling, which contains a crista. When the head moves the fluid in the canals presses on the cristae, which register the movement and send nerve impulses to the brain.
