Corrugator
The corrugator supercilii is a small, pyramidal muscle of facial expression located at the inner extremity of the eyebrow and beneath the occipito-frontalis and orbicularis palpebrarum muscles on each side of the face.
The points of origin and insertion, and the actions of the corrugator muscle:
| Origin: | Superciliary ridge of the frontal bone |
| Insertion: | Deep surface of the skin opposite the middle of the orbital arch |
| Actions: | Affects facial expression by moving skin tissues in the area around the corrugator supercilii muscles just above the eyes |
Note that the corrugator supercilii (described on this page) is not to be confused with the corrugator cutis ani, which is located around the anus.
The corrugator supercilii is one of the muscles of the head, neck, and face taught as part of many courses in Indian Head Massage. As this is a popular therapy we have included several pages that may be of interest to students of Indian Head Massage. See, for example, the page about skeletal structures of the head and neck.
See the page about Facial Muscles to view the location of the corrugator muscle.
(This page consists of an interactive, rather than just a labelled, diagram, so you'll have to test yourself by guessing which muscle is the corrugator until you find the correct label.)
