"origin: anterior end of the galea aponeurotica"
"insertion: superior border of orbicularis oculi muscle and the overlying skin of the eyebrow; there is no attachment to the skull 2"
"arterial supply: frontal branch of the superficial temporal artery laterally and the supratrochlear and supraorbital arteries medially 3"
"innervation: temporal branches of the facial nerve"
"action: pulling of the scalp anteriorly, wrinkling of the forehead skin, and elevation of the eyebrows"
"The frontalis muscle (TA: musculus frontalis) is a paired muscle extending from the supraorbital region to the level of the coronal suture. Flat and quadrilateral in shape, it is one of the facial muscles. Along with the occipitalis muscle, it forms the occipitofrontalis muscle due to a common tendon sheet attachment; the galea aponeurotica 1."

"The frontalis muscle has clinical significance in relation to facial aesthetics and pathology related to defects of soft tissue and imbalances of motor control. The frontalis muscle is also used in reconstruction; for example frontalis myofascial flaps for cranialisation of the frontal sinus 3."
