Ear Canal

What is the Ear Canal?

The ear canal is a tube that runs from the outside of the ear to the eardrum. It is about an inch long and is lined with skin. The ear canal helps to collect sound waves and directs them to the eardrum.

How do you clean your ear canal?

The ear canal is self-cleaning. You should not put anything in your ear canal, including cotton swabs, as this can push earwax deeper into the canal and damage the eardrum. If you have excessive earwax, you can see an audiologist or doctor who can safely remove it.

What happens in the ear canal?

Sound waves enter the ear canal and travel down the canal to the eardrum. The eardrum vibrates in response to the sound waves. These vibrations are then transmitted to the middle ear, where they are converted into electrical signals that are sent to the brain.

What are the different types of canals in the ear?

There are three types of canals in the ear:

  • The external auditory meatus: This is the ear canal that runs from the outside of the ear to the eardrum.
  • The middle ear: This is the air-filled space behind the eardrum. It contains three tiny bones (ossicles) that transmit sound waves to the inner ear.
  • The inner ear: This is the part of the ear that contains the cochlea, which is responsible for converting sound waves into electrical signals.

What are the three parts of the ear canal?

The ear canal is divided into three parts:

  • The outer third: This part of the canal is lined with skin that contains hair and sebaceous glands. The hair helps to trap dust and dirt, and the sebaceous glands produce earwax, which helps to protect the canal from infection.
  • The middle third: This part of the canal is lined with cartilage.
  • The inner third: This part of the canal is lined with bone.

Conclusion

The ear canal is an important part of the hearing system. It helps to collect sound waves and directs them to the eardrum. The ear canal is also self-cleaning, so you should not put anything in your ear canal, including cotton swabs. If you have excessive earwax, you can see an audiologist or doctor who can safely remove it.
