Semicircular Canals

The semicircular canals are the three fluid-filled tubes of the bony labyrinth, forming three loops; the superior semicircular canal, the posterior semicircular canal, and the horizontal semicircular canal. Being part of the vestibular system, they are involved with balance and equilibrium as they have motion sensors inside (sensory epithelium containing hair cells). The type of fluid each of the canals is filled with is endolymph.
