MUSCULUS CORRUGATOR SUPERCILII Meaning and
Definition
-
Musculus corrugator supercilii is a term used in anatomy to describe a specific muscle located in the face. It is Latin in origin, with "musculus" meaning muscle, "corrugator" derived from the verb "corrugare" meaning to wrinkle, and "supercilii" referring to the eyebrows.
The musculus corrugator supercilii is a small facial muscle that is responsible for wrinkling or furrowing the forehead. It is formed by a narrow band of muscle fibers located within the layer of the skin and muscle beneath the eyebrows. The muscle originates from the frontal bone just above the nasal bone, passes horizontally and diagonally upward, and inserts into the connective tissue of the eyebrows.
When the musculus corrugator supercilii contracts, it pulls the eyebrows downward and medially, causing vertical wrinkles or furrows to appear between the eyebrows. This muscle is involved in facial expressions related to anger, concentration, and sadness. It is particularly active during frowning or when an individual is expressing negative emotions.
Understanding the anatomy and function of the musculus corrugator supercilii is important in fields such as facial reconstruction, plastic surgery, and neurology, as it plays a role in various medical conditions and cosmetic procedures. By studying this specific muscle, researchers and medical professionals can gain insight into the complex movements and expressions of the human face.
