Otolith organs are responsible for?
The otolith organs provide information about the position of the head with respect to gravity. When the head is bent away from its normal upright position, otoliths (small calcium carbonate crystals within the utricle and saccule are pulled downward by gravity. The crystals bend the stereocilia on the hair cells, causing the hair cells to depolarize. Depolarization of the hair cells stimulates the vestibular iterse fibers. Bending the head in different directions causes different otoliths to move. Therefore, the paicular group of vestibular nerve fibers that is stimulated signals the direction in which the head bends.
Producing the vestibular-ocular reflex
Detecting the position of the head in space
Producing rotary nystagmus
Detecting angular acceleration
