8. Ear Canal Anatomy

The ear canal is a tube of solid bone. The skin lining the ear canal is smooth and highly sensitive. The tympanic membrane, a circular layer of tissue in the ear canal, marks the spot between the external ear and the middle ear. This membrane is also known as the eardrum and is key to hearing. The eardrum is tough and flexible, making it difficult to damage, but objects inserted into the ear can perforate it, causing hearing loss.
