Ear tags are typically placed in which anatomical structure of the ear?

• A. Ear canal
• B. Auricle
• C. Tympanic membrane
• D. Pinna

Answer: (B)

Ear tags are placed in the outer ear where they can be applied to the exposed skin of the ear flap. This region, the auricle (also called the pinna), is easily accessible and provides a stable spot for the tag. In contrast, the ear canal is a narrow passage leading to the eardrum, and the tympanic membrane is the eardrum itself—both are internal and would be risky and impractical for tagging. So the tag goes into the auricle/pinna.
