face

The face is the front of an animal's head that features the eyes, nose and mouth, and through which animals express many of their emotions. The face is crucial for human identity, and damage such as scarring or developmental deformities may affect the psyche adversely. Structure The front of the human head is called the face. It includes several distinct areas, of which the main features are: The forehead, comprising the skin beneath the hairline, bordered laterally by the temples and inferiorly by eyebrows and ears The eyes, sitting in the orbit and protected by eyelids and eyelashes The distinctive human nose shape, nostrils, and nasal septum The cheeks, covering the maxilla and mandible (or jaw), the extremity of which is the chin The mouth, with the upper lip divided by the philtrum, sometimes revealing the teeth Facial appearance is vital for human recognition and communication. Facial muscles in humans allow expression of emotions. The face is itself a highly sensitive region of the human body and its expression may change when the brain is stimulated by any of the many human senses, such as touch, temperature, smell, taste, hearing, movement, hunger, or visual stimuli.
