Balancing stone from inner ear. Coloured scanning electron micrograph (SEM) of crystals of calcium carbonate on the surface of an otolith. An otolith or otoconium is a calcified stone that is found in the otolith organs of the inner ear. They are attached to sensory hairs,and,when the head tilts,the stones' movements cause nerve impulses that allow a sense of balance and orientation to be maintained. In humans,otoconia range from 3-30 microns (millionths of a metre) across. Magnification unknown | |
