Within the vestibule, there are two depressions, or 'rooms'. One of the two depressions, the utricle (recessus ellipticus) is located posteriorly, and the other depression, the saccule (or recessus sphæricus), is located anteriorly. Both of them have hair cells, and on the hair of them, otolith, a heavy structure that moves with gravity, is attached.
