Eyebrows are a very significant aspect of our appearance. They are one of
the most distinctive features that make up our faces, and we pay a lot of

/Eyebrow/
Latin /supercilium/
MeSH /Eyebrows/

The *eyebrow* is an area of thick, delicate hairs above the eye that

debris from falling down into the eye socket, but they are also important
to human communication and facial expression. It is not uncommon for people
– women in particular – to modify their eyebrows by means of hair
addition, removal, makeup, tattoo, or piercings.

hypothesis). The typical curved shape of the eyebrow (with a slant on the
side) and the direction in which eyebrow hairs are pointed, make sure that
moisture has a tendency to flow sideways around the eyes, along the side of
the head and along the nose.^[/citation needed/] The slightly protruding
brow ridges of modern humans could also be used as a defense structure
against the floods of moisture. Desmond Morris, discussing the possible
function of the eyebrow in human evolution, criticized this suggestion as
non-effective ^[1] and suggested that the primary function of the eyebrows
is to signal the changing moods of their owners. Together with the brow
ridges, the eyebrows also shade the
