Ear Canal Anatomy, Functions, Pain Causes & Infections
The ear canal, also called the external auditory meatus (EAM), is a structure similar to a tube that is shaped like an "S". It extends from the outer ear or pinna (the part of the ear that is visible) to the eardrum, which is also known as the tympanic membrane. This channel is not just a straight tunnel; Instead, it bends in a way that helps direct sound waves to the eardrum, and in total ,it is approximately 2.5 cm long in adults.
