Canalith Debris in BPPV Is Typically Derived From Which Inner Ear Structure?

Explanation:
Canalith debris in BPPV comes from the otolith organs in the vestibule, specifically the utricle and saccule. These structures contain otoconia, crystals that help detect gravity and linear acceleration. When these crystals become dislodged, they can travel into a semicircular canal and move with head position, momentarily deflecting the hair cells and triggering vertigo and nystagmus. The cochlea handles hearing, and while the semicircular canals are where the symptoms occur, the source of the debris is the otolith organs themselves, located in the vestibule.
