The<unk>  (Greek philtron, from philein, "to love; to kiss"), also known as the infranasal depression, is the vertical groove in the upper lip, formed where the nasomedial and maxillary processes meet during embryonic development.
The<unk>  allows humans to express a much larger range of lip motions than would otherwise be possible, which enhances vocal and non-verbal communication.
