What is often referred to as the center of the facial expression?

The angulus oris, often referred to as the center of facial expression, is the anatomical area located at the corners of the mouth where the upper and lower lips meet. This region plays a significant role in conveying emotions through facial movements, such as smiling, frowning, and other expressions that involve lip movement. The control and positioning of the muscles around the angulus oris are crucial for effective non-verbal communication, making it central to facial expressions.

Understanding this concept highlights the importance of facial anatomy in both professional practices related to mortuary science and in the broader context of human interaction. The angulus oris serves as a focal point for expressions, exemplifying how small areas can have a significant impact on perception and emotional conveyance.
