Muscle that compresses the lips (M. Constrictor Labiorum)

Facial muscles are extremely important for chewing, speaking, making emotional expressions and controlling facial expressions. But that's not all these muscles do. They are also part of a whole mechanism that makes our lips ideal for transmitting information about how we feel.

The muscle that is responsible for this transmission of information is the m.constrictor labium, or the tensor labium muscle. This muscle is located in the layer of musculature above the upper lip, and it has two functions: aiding swallowing and conveying facial expression.

The function of M. conlictus labii is to maintain their upright position when a person closes their mouth completely. It also helps guide solids, such as tablets, into the mouth. Here the most important function of the muscle is the transmission of facial expression; it controls and changes the shape of the mouth during conversation. The emotional side of smiling and frowning is controlled by the tension of M. constriction labii. These actions are well known and are conveyed by hand in the form of gestures. A tense muscle during various human movements affects the condition of the facial muscles and can cause wrinkles. This is why it is so important to take care of the condition of your muscles and avoid various activities that can cause them to become overstrained.

Overall, M. Conlictus labio is an important element of our mechanism that helps convey emotions, facial expressions and keeps our lips in a vertical position that helps us make mouth movements controlled by the articulatory apparatus.
