Orbicularis oculi muscle
Facial muscle that closes the eyelids / From Wikipedia, the free encyclopedia
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.
