The front of the human head is called the face. It includes several distinct areas,[3] 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 mandibula (or jaw), the extremity of which is the chin.
The mouth, with the upper lip divided by the philtrum, sometimes reveals 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 five senses: touch, temperature smell, taste, hearing, and visual stimuli.[4]
