Cards in this deck (16)
- 1Muscles of the headThe muscles of the face are important because they open and close the apertures in our faces-our eyes, nose, and mouths. They play important roles in our body language as they control the facial expressions. Wrinkles are the reflections of the expressions we have used throughout our lives. Wrinkles lie perpendicular to the muscle fibers.
