www.faasafety.govOtolith organs The otolith organs are small sacs at the base of the semicircular canals. They are embedded with sensory hairs and contain a gelatinous membrane with chalk-like crystals – called otoliths. As the head or body moves, the movement of the membrane against the sensory hairs registers gravity.
Canalith Repositioning Procedure (CRP)

In most cases of BPPV, the canaliths enter the posterior semi-circular canal where they become trapped due to the anatomy of the canal and the effects of gravity. The canaliths move in the canal when

Dizziness & balance problems - Brain and Spine
www.brainandspine.org.ukThere are also two structures called the “otolith organs.” These tell your brain about the position of your head and can also detect when your head is moving in a straight line. Dizziness or vertigo may occur when the signals from your right and left vestibular systems provide conflicting information, or if your brain thinks your
