The face is a central body region of sense and is also very central in the expression of emotion among humans and among numerous other species. The face is normally found on the anterior (frontal, rostral) surface of the head of animals[citation needed] or humans,[1] although not all animals have faces.[2] The face is crucial for human identity,
and damage such as scarring or developmental deformities have effects
stretching beyond those of solely physical inconvenience.
