Corrugator supercilii muscle
The corrugator supercilii muscle is a muscle that sits just above the eye and lowers and centers the eyebrow when contracted. The corrugator motion wrinkles the skin between the eyes in the facial expression of pain or anger.
The corrugator originates from behind the eyebrows on the medial superciliary arch.
The corrugator is innervated by the temporal branch of the facial nerve (CN VII).
