Study Notes
Ear Anatomy and Functions
- Cochlea: A coiled, bony, fluid-filled structure in the inner ear; responsible for converting sound waves into neural signals.
- Ear Canal: Also known as the external auditory canal; a passage that allows sound to travel to the eardrum.
- Eardrum: A membrane in the middle ear that vibrates in response to incoming sound waves, initiating the hearing process.
Ear's Small Bones
- Hammer (Malleus): The outermost bone of the three ossicles; it transmits vibrations from the eardrum to the anvil.
- Anvil: A tiny bone that bridges the hammer and stirrup; it passes vibrations from the hammer to the stirrup.
- Stirrup: Known as the smallest bone in the human body; it transfers vibrations from the anvil directly to the cochlea.
Additional Structures
- Auditory Nerve: A bundle of nerve fibers that relays auditory information from the cochlea to the brain for processing.
- Pinna: The visible part of the ear that helps capture sound and channels it toward the eardrum.
- Semicircular Canals: Structures in the inner ear that contribute to maintaining balance and spatial orientation.
- Eustachian Tube: Connects the middle ear to the nasopharynx; it helps equalize air pressure on either side of the eardrum, essential for proper hearing.
