Which structure is also called the auricle?

• A. Pinna (Auricle)
• B. Tympanic Membrane
• C. External Auditory Canal
• D. Middle Ear

Answer: (A)

The outer ear flap you can see on the side of the head is the auricle, also called the pinna. It collects sound waves and helps funnel them into the ear canal toward the eardrum. The tympanic membrane is the eardrum, the external auditory canal is the passage leading to that eardrum, and the middle ear is the space behind the eardrum that houses the small hearing bones. Because the auricle and pinna are two names for the same outer ear structure, this is the best answer.
