ORIGIN
CLINICAL SIGNIFICANCE
MEDIAL END OF SUPERCILIARY ARCHES, FIBERS OF ORBICULARIS
OCULI MUSCLE
CORRUGATOR SUPERCILII IS A SMALL, PYRAMIDAL MUSCLE
THAT BELONGS TO THE CIRCUMORBITAL AND PALPEBRAL
GROUP. CORRUGATOR SUPERCILII EXERTS TRACTION ON THE
SKIN ABOVE THE SUPRAORBITAL MARGIN. THE COMBINED
ACTIONS OF THE ORBICULARIS OCULI AND CORRUGATOR
MUSCLE PULL THE EYEBROWS MEDIALLY AND INFERIORLY. THIS

FUNCTIONS,
SUCH
AS PROTECTING THE EYES FROM BRIGHT SUNLIGHT OR RAIN.
ADDITIONALLY, THE CORRUGATOR SUPERCILII MUSCLES SERVE
AS MIMETIC MUSCLES THAT CONTRACT WHEN ONE IS ANGERED
OR PERPLEXED.
SCIENTIFIC STUDIES CONFIRMED THAT
CORRUGATOR SUPERCILII EXHIBITED GREATER MUSCLE
ACTIVITY IN NEGATIVE FACIAL EXPRESSIONS. THEREFORE,
CORRUGATOR SUPERCILII MUSCLES ACTIVITY CAN HELP
EVALUATE DIFFERENCES IN POSITIVITY-NEGATIVITY BIAS AMONG
DIFFERENT PEOPLE. TOGETHER WITH OTHER MUSCES OF
PALPEBRAL GROUP, CORRUGATOR SUPERCILII MAINTAINS A
BALANCED BROW POSITION AND SHAPE.
