Final answer:
The utricle, saccule, and the three semicircular canals are the inner ear structures that convey impulses to the brain via the vestibular nerve, aiding in balance and spatial orientation. These impulses are processed in the brain to coordinate movement and stabilize vision.
Step-by-step explanation:
The inner ear structures that convey impulses to the brain via the vestibular nerve include the utricle, saccule, and the three semicircular canals. These structures are part of the vestibular system which is responsible for maintaining balance and spatial orientation. The sensory nerves from these structures form part of the vestibulocochlear nerve (CN VIII), which transmits equilibrium information from the inner ear to the brain for processing.
Higher-level processing of these signals involves communication from the hair cells of the utricle, saccule, and semicircular canals through bipolar neurons to the cochlear nucleus in the medulla. This information is then relayed to various brain areas, including the cerebellum, somatosensory cortex, and the optic muscles to coordinate movements and stabilize vision.
