Surprise is expressed in the face by the following features:
- Eyebrows that are raised so they become curved and high.
- Stretched skin below the eyebrows.
- Horizontal wrinkles across the forehead.
- Open eyelids-- the upper lid is raised and the lower lid is drawn down, often exposing the white sclera above and below the iris.
- Dropped jaw so that the lips and teeth are parted, with no tension around the mouth.
