The term "auricular appendage" refers to the external ear, also known as the pinna. However, there are several synonyms for this term to describe the same body part. These synonyms include the auricle, earflap, and earlobe. The auricle is the most commonly used synonym for the auricular appendage and is derived from Latin "auris" meaning ear. Earlobe is used specifically to refer to the fleshy, lower part of the ear. Earflap is a more colloquial term that refers to the part of the ear that flaps in the wind. Despite their differences, all of these synonyms describe the same part of the human anatomy.
