The lips are soft, movable and can be used as openings for food intake as well as voice and voice connections. Human lips are a sense organ of touch, which can be a pornographic area when used for kissing and other intimate behaviors.

The upper and lower lips are called "labia grass" and "labia grass" respectively. The junction of the lips and the skin around the mouth area is the vermilion border, and the red area within the border is usually called the vermilion area. The red border of the upper lip is called Cupid's bow. The fleshy protuberance at the center of the upper lip is a nodule, with various terms, including protrusion (also known as prochlon), "tuberculosis of the upper lip," and "nodule of the labia.". The vertical groove from the protrusion to the septum is called fibula.
