Final answer:
The vestibulocochlear nerve (CN VIII) is purely sensory and has two main functions: hearing and balance.
Step-by-step explanation:
The vestibulocochlear nerve (CN VIII) is purely sensory and has two main functions: hearing (auditory function) and balance (vestibular function).
- The auditory function of CN VIII involves transmitting sound information from the cochlea in the inner ear to the brain for processing. This allows us to hear and interpret different sounds.
- The vestibular function of CN VIII involves detecting changes in head position and movement to maintain balance and spatial orientation. The vestibular components of CN VIII send signals to the brain about the position and movement of the head, which helps us maintain balance and coordination.
