Quizplus · Accepted Answer

The membranous ampulla is a specialized structure at the base of each semicircular canal that contains the crista ampullaris, which is composed of hair cells and a gelatinous dome-shaped mass called the cupula. The cupula, therefore, is a component of the crista ampullaris located within the membranous ampulla. Option B is incorrect because the utricle and saccule are not found in the ampulla, but rather in the vestibule. Option C is incorrect because it describes two separate structures within the inner ear, neither of which corresponds to the cupula. Option D is incorrect because it describes the location of the cochlear duct and does not pertain to either the membranous ampulla or the cupula.
