The corrugator supercilii muscle originates from the frontal bone at the medial portion of the superciliary arch.


The corrugator supercilii muscle extends in a superolateral direction and inserts into the skin above the supraorbital margin.

Key Features & Anatomical Relations

The corrugator supercilii lies deep to the frontal belly of occipitofrontalis and the orbicularis oculi muscles.


The corrugator supercilii muscle works in conjunction with orbicularis oculi muscle, drawing the eyebrows in an inferomedial direction. This action aids in shielding the eyes and is also involved in frowning (Standring, 2016).
