Levator Labii Superioris Alaeque Nasi Muscle

The levator labii superioris alaeque nasi muscle is, translated from Latin, the "lifter of both the upper lip and of the wing of the nose". It has the longest name of any muscle in an animal. The muscle is sometimes documented as Otto's muscle, a term coined by a student of anatomy due to frustration with the name being so long and tedious to write. The muscle is attached to the upper frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip. It dilates the nostril and elevates the upper lip, enabling one to snarl. Elvis Presley is famous for his use of this facial expression, earning the muscle this nickname "The Elvis muscle".
