Question

what is PHILTRUM ??????????​

Answer 1

Answer:

The philtrum is the midline groove in the upper lip that runs from the top of the lip to the nose.

Function. In most mammals, the philtrum is a narrow groove that may carry dissolved odorants from the rhinarium or nose pad to the vomeronasal organ via ducts inside the mouth. For humans and most primates, the philtrum survives only as a vestigial medial depression between the nose and upper lip.
