The frontalis (sometimes also referred to as the "frontal portion") is a thin quadrilateral muscle that is intimately adherent to the superficial fascia.
The points of origin and insertion, and the actions of the frontalis muscle:
|Origin:||Galea aponuerotica (a flat tendon attached to both the frontalis and occipitalis muscles)|
|Insertion:||Integument (skin) above the orbits of the eyes|
The frontalis 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 frontalis 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 frontalis until you find the correct label.)
