Question

Otoliths are

Quizplus · Accepted Answer

Otoliths are small stones that are attached to hair cells in the utricle and saccule of the inner ear. They play a role in detecting linear acceleration and head positioning.

Note: B is incorrect because vestibular nerves do not make direct contact with hair cells. Hair cells in the inner ear are actually stimulated by the movement of fluid in the canals, which then sends a signal to the vestibular nerves. C is incorrect because particles (or endolymph) in the semicircular canals provide information about rotational acceleration, not linear acceleration or head positioning. D is incorrect because membranes in the saccule and utricle do not play a major role in the detection of linear acceleration or head positioning.
