The orbicularis oculi is a muscle in the face that closes the eyelids. It arises from the nasal part of the frontal bone, from the frontal process of the maxilla in front of the lacrimal groove, and from the anterior surface and borders of a short fibrous band, the medial palpebral ligament.he frontalis muscle, which runs from the upper forehead, halfway between the coronal suture (which traverses the top of the skull) and the top edge of the orbit, attaches to the eyebrow skin. Since it pulls the eyebrows upward, it is the antagonist of the orbicularis oculi.
