Definition
The vestibulocochlear nerve is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain. It is essential for hearing and maintaining balance while moving or in stationary positions.
A spiral-shaped cavity in the inner ear that plays a key role in converting vibrations into neural messages for hearing.
Semicircular canals: Three looped tubes in the inner ear filled with fluid that help maintain balance by detecting head rotation.
Cranial nerves: Twelve pairs of nerves that emerge directly from the brain (not through the spinal cord) and reach various parts of the head and neck to control motor and sensory functions
