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 are tabulated below:
Origin |

Galea aponuerotica (a flat tendon attached to both the frontalis
and occipitalis muscles).

This is one of the muscles of the head, neck, and face that is included
on the syllabus of many courses in Indian
Head Massage. As this is an increasingly popular therapy we have
added several revision pages that may be helpful to students of Indian
Head Massage. See for example, the page about Skeletal
Structures of the Head and Neck.
To view the location of the frontalis
muscle, see the page about Facial
Muscles.
Note that this page consists of an interactive (rather than a simply
labelled) diagram, so you'll have to test yourself by guessing which
muscle is the frontalis until
you find the correct label. It's a fun way to learn !
