Human Facial Expressions

Human facial expressions are non-verbal signals that communicate emotions and reactions, ranging from happiness and surprise to anger and sadness. These expressions are generated by the movement of facial muscles under the control of the nervous system. They serve as social cues, helping others understand how we feel and fostering effective communication. While some expressions are universal across cultures, others are influenced by social norms and individual differences. Overall, facial expressions are a vital part of human interactions, providing immediate and often subconscious insights into a person's emotional state.
