VESTIBULAR SACS

two sacs inside the inner ear, which, combined with the semicircular canals, make up the vestibular apparatus. The vestibular sacs react to gravity and type data regarding the head's position in space.

VESTIBULAR SACS: "Low-frequency arousal of the vestibular sacs can generate vertigo-like symptoms and rhythmic eye motions known as nystagmus."
