hair cells

Hair cells are specialized sensory cells found in the inner ear, crucial for hearing and balance. They have tiny hair-like structures called stereocilia on their surface. When sound waves or head movements cause these stereocilia to bend, the hair cells convert this mechanical movement into electrical signals. These signals are then sent to the brain, allowing us to perceive sound and maintain our sense of balance. Damage to hair cells can lead to hearing loss or balance disorders, highlighting their importance in our auditory and vestibular systems.
