In
human anatomy, the
forehead is an area of the
head bounded by three features, two of the
skull and one of the
scalp. The top of the forehead is marked by the hairline, the edge of the area where hair on the scalp grows. The bottom of the forehead is marked by the
supraorbital ridge, the bone feature of the skull above the eyes. The two sides of the forehead are marked by the
temporal ridge, a bone feature that links the supraorbital ridge to the
coronal suture line and beyond.
