where does the orbicularis oculi insert
Orbicularis Oculi. Orbicularis means circular muscle and oculi means eye. This is a circular (sphincter) muscle that goes around the eye. Fibers anchor the frontal bone and maxillary bone and inserts into the eyelid so that when it contracts it closes the eye.he origin of this is the body of the mandible and the insertion is the skin/muscle of the lower lip. Note the triangularis/depressor anguli oris insertion is at the corner of the mouth while the depressor labii inferioris is more medial.
