The ear canal is a tube that runs from the outer ear to the eardrum. It is lined with skin and contains small hairs and glands that produce earwax. The ear canal helps to protect the eardrum from dirt and debris, and it also helps to amplify sound waves as they travel to the eardrum.
The ear canal is important for hearing, and it can be prone to problems. For example, the ear canal can become blocked with earwax, or it can be infected with bacteria or viruses. When this happens, it can cause pain and hearing loss.« Back to Glossary Index
