What is "inner ear"?

The inner ear is a complex structure located deep within the skull and is responsible for both hearing and balance. It consists of the cochlea, semicircular canals, and vestibule. The cochlea is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The semicircular canals and vestibule play a crucial role in maintaining balance and detecting changes in head position and movement. The inner ear is filled with fluid and contains delicate sensory cells that help transmit auditory and vestibular information to the brain. It is a vital part of our sensory system, enabling us to hear and maintain our sense of balance.
