The auditory and vestibular systems are functionally and neuroanatomically interrelated as they both respond to vibration, are housed in the same bony structure, and fibers carrying auditory and vestibular inputs form cranial nerve VIII (CNVIII).

Question

Quizplus · Accepted Answer

The auditory and vestibular systems are indeed interrelated both functionally and neuroanatomically. They respond to different forms of mechanical stimuli (sound and head movements, respectively), are housed within the bony labyrinth of the inner ear, and their sensory inputs are carried by the vestibulocochlear nerve, also known as cranial nerve VIII (CNVIII).
