Question

Quizplus · Accepted Answer

The hair cells are the receptive cells for the functions of the utricle and saccule. These hair cells have small hair-like projections, known as stereocilia, which are displaced by the movement of otoliths, causing the cells to depolarize and send signals to the brain through the vestibular nerve. Choice A is incorrect because otoliths are small calcified particles that are displaced by the movement of the head and stimulate the hair cells. Choice C is incorrect because cupula and endolymph are structures in the semicircular canals that play a role in detecting angular motion, not in the utricle and saccule. Choice D is incorrect because cilia are not found in the inner ear and do not play a role in vestibular function.
