The vestibule is the central cavity of which structure?

Explanation:
The vestibule is the central cavity located within the bony labyrinth of the inner ear. It serves as the hub that connects the cochlea, which handles hearing, with the semicircular canals, which sense head motion. Inside the vestibule are the utricle and saccule, organs that detect linear acceleration and gravity. The cochlea is a separate, spiral structure dedicated to hearing, while the outer ear auricle is unrelated to the vestibule.
