C
The semicircular canals are three bony, fluid-filled loops in the osseous labyrinth of the inner ear associated with balance and equilibrium. The posterior, superior, and lateral canals, all about 0.8 mm in diameter and perpendicular to each other, open into the cochlea. The receptor organ for hearing is the cochlea, which is a snail-shaped structure made up of three compartments. The openings from the middle ear to the inner ear are the oval window at the end of the stapes and the round window.
