The inner ear is a complex structure located deep within the skull, responsible for both hearing and balance. It consists of the cochlea, which converts sound vibrations into electrical signals for the brain, and the vestibular system, which helps maintain balance and spatial orientation. The inner ear is filled with fluid and lined with tiny hair cells that respond to sound waves and changes in head position.
The inner ear is protected by the temporal bone of the skull and is connected to the middle ear through the oval window. Any damage to the inner ear can lead to hearing loss or balance disorders, highlighting its crucial role in sensory perception.
