Origin of otolith:
A small particle, comprised mainly of calcium carbonate, found in the inner ear of vertebrates, being part of the balance sense.
Origin: From ωτο (ōto), stem of οὖς + λίθος.
An otolith, also called statoconium or otoconium is a structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. The saccule and utricle, in turn, together make the otolith organs. They are sensitive to gravity and linear acceleration. Because of their orientation in the head, the utricle is sensitive to a change in horizontal movement, and the saccule gives information about vertical acceleration.
