The utricle and saccule of the membranous labyrinth lie within which part of the bony labyrinth?

• A Cochlea
• B Mastoid antrum
• C Internal acoustic meatus
• D Vestibule ✓

Explanation

The vestibule is the central ovoid chamber of the bony labyrinth, situated medial to the middle ear, and it houses the utricle and saccule with their maculae. The three semicircular canals open off the posterior wall of the vestibule and contain the semicircular ducts with their ampullae. The cochlea, lying anterolaterally, contains the cochlear duct, not the otolith organs.
