The musculo elevador del labio superior, also known as the levator labii superioris muscle, is an important muscle located in the human face. It is responsible for the elevation of the upper lip, and when it contracts, it also causes the nostrils to dilate. This muscle is located in the upper lip area, and it is one of the most important muscles for human facial expressions.
How Does the Musculo Elevador del Labio Superior Work?
The musculo elevador del labio superior originates from the infraorbital margin of the maxilla, which is a bone located in the upper part of the face. It then inserts into the skin of the upper lip. This muscle works by contracting, which causes the upper lip to elevate. It also helps to dilate the nostrils, which is important for breathing.
The Role of the Musculo Elevador del Labio Superior in Facial Expressions
The musculo elevador del labio superior is one of the most important muscles for human facial expressions. It is involved in a wide range of expressions, including smiling, sneering, and snarling.

The Musculo Elevador del Labio Superior in Speech
The musculo elevador del labio superior is also important for speech. It is involved in the production of certain sounds, including the labiodental consonants, such as 'f' and 'v'.
