Question

Quizplus · Accepted Answer

The otolith organs, which include the utricle and saccule, are part of the vestibular system in the inner ear. They are sensitive to movement, acceleration, and gravity because they contain tiny crystals called otoliths in a gelatin-like substance, which helps in detecting linear accelerations and head tilts.
