Anatomy of the Ear
- Pinna (auricle) – collects and funnels sound into the ear canal.
- Ear canal (external auditory meatus) – directs sound into the ear.
- Eardrum (tympanic membrane) – changes sound into vibrations.
- Hammer, anvil and stirrup (malleus, incus and stapes) – this chain of three small bones (ossicles) transfers vibrations to the inner ear.
- Inner ear (cochlea) – contains fluid and highly sensitive "hair" cells. These tiny hair-like structures move when stimulated by sound vibrations.
- Vestibular system – contains cells that control balance.
- Auditory nerve – leads from the cochlea to the brain.
