The levator labii superioris alaeque nasi muscle is, translated from Latin, the "lifter of the upper lip and of the wing of the nose". It has the longest name of any muscle in an animal.
Attachment
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.
Action
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".
Mnemonic
The long name of muscle can make it hard to remember. A mnemonic to remember its name is, "Little Ladies Snore All Night." Snore- because it is the labial elevator closest to the nose.
