Levator anguli oris is a facial muscle primarily responsible for elevating the corners of the mouth, playing a key role in expressions like smiling. Located at the angle of the mouth, it originates from the maxilla and inserts into the skin at the angle of the mouth. Its primary function is to assist in facial expressions by lifting the mouth corners upward.
The name "Levator anguli oris" is derived from Latin, where "levator" means "to lift," "anguli" means "angle," and "oris" means "of the mouth." This describes its function and location in the facial structure.
Without the levator anguli oris, the human body would struggle to perform expressions that involve lifting the corners of the mouth, such as smiling or expressions of joy, impacting non-verbal communication significantly.
