Study Notes
External Ear
- The external auditory canal, also known as the ear canal, is a tube that connects the outer ear to the eardrum.
- It is lined with cartilage and contains hairs that help to filter out dust and other debris.
Middle Ear
- Located in the temporal bone, the middle ear contains three small bones called ossicles: the malleus, incus, and stapes.
- These bones are responsible for transmitting sound vibrations from the eardrum to the inner ear.
- The eardrum, also known as the tympanic membrane, separates the middle ear from the outer ear.
- The middle ear also contains a tube called the Eustachian tube, which connects to the back of the throat and helps to regulate air pressure.
Inner Ear
- The inner ear contains the labyrinth, a complex structure filled with fluid that is responsible for hearing and balance.
- The labyrinth has three parts: the cochlea, vestibule, and semicircular canals.
- The cochlea is responsible for hearing, while the vestibule and semicircular canals are responsible for balance and equilibrium.
- The inner ear also contains the auditory nerve, which carries sound signals to the brain.
Hearing and Balance
- Hearing and balance are both affected by the movement of fluid in the labyrinth.
- When sound waves reach the eardrum, they cause the fluid in the cochlea to vibrate, which stimulates the auditory nerve.
- The vestibule and semicircular canals are filled with a gel-like substance that moves in response to changes in head position, which helps to maintain balance and equilibrium.
- Any damage to the inner ear or the auditory nerve can lead to hearing loss or balance disorders.
