Question

Membranous labyrinth is concerned with

• A. Balancing
• B. Hearing
• C. Sound production
• D. All the above

Answer 1

The correct option is D All the above

There are actually two labyrinths of the inner ear, one inside the other—the membranous labyrinth contained within the bony labyrinth. The bony labyrinth consists of a central chamber called the vestibule, the three semicircular canals, and the spirally coiled cochlea. Within each structure, and filling only a fraction of the available space, is a corresponding portion of the membranous labyrinth: the vestibule contains the utricle and saccule, each semicircular canal its semicircular duct, and the cochlea its cochlear duct.
