Final answer:
The correct sequence for the inner ear structures from largest to smallest is the bony labyrinth, cochlea, spiral ganglia, and hair cells.
Step-by-step explanation:
The sequence that correctly arranges the structures of the inner ear from the largest and most inclusive to the smallest and most specific is: bony labyrinth (inner ear), cochlea, spiral ganglia, and hair cells (sensory cells). The bony labyrinth is the most inclusive structure, housing the cochlea and vestibule, which are responsible for hearing and balance. The cochlea, a coiled tube, contains the spiral ganglia, which in turn consist of sensory neurons. These neurons end in the hair cells, which transduce sound into neural signals.
