Miscellaneousi

Miscellaneous

Otoconia are minute biomineral particles embedded in a gelatinous membrane that overlies the sensory epithelium in the inner ear. Gravity and acceleration cause the octoconia to deflect the stereocilia of sensory hair cells. Otoconia are required for normal processing of information regarding spatial orientation and acceleration.
