Otolith organs are able to sense gravitational changes and linear acceleration that comes from movement in a straight line. Also called the utriculus, the utricle occupies the bony labyrinth of the inner ear, nestled between the cochlea and the semicircular canals. Otolithic organs detect movement depending on their orientation. Animals or humans without otolithic organs are imbalanced. The utricle detects movement on the horizontal plane of the head, and the saccule detects vertical motion. The utricle is composed of a mass of tiny calcareous stones covered in hair cells embedded in a jelly-like substance containing the calcareous stones.
