D) conducting sound waves through endolymph.

Question

Quizplus · Accepted Answer

The utricle and saccule are responsible for detecting the position of the head, including changes in linear acceleration and gravity. They both contain hair cells that are stimulated by the movement of otoliths, small calcium carbonate crystals, in response to changes in position or motion of the head. This information is sent to the brain via the vestibular nerve, which helps us maintain balance and spatial orientation. The utricle and saccule are not involved in transmitting or changing sound waves, nor do they conduct sound waves through endolymph.
