Front part of the head, extending from the forehead to the chin and housing the eyes, nose, mouth, and jaws. The receding of the jaw and the increasing size of the brain in human evolution has made the face essentially vertical, with two distinctively human features: a prominent, projecting nose and a clearly defined chin. The face and braincase follow different patterns of growth. While the face grows more slowly, it ends up much larger compared to the braincase in adults than at birth. The facial muscles move the features to express emotion.
