Introduction

the superior aspect of the midline forehead there is no muscle, but a fascial band.

The usual action of the m. frontalis is to raise the eyebrows in the expression of surprise and even higher with fright, and to furrow the forehead with transverse lines with thought. The eyebrows have one elevator and three opponents as depressors: the m. corrugator, the m. procerus and the m. orbicularis oculi. The m. frontalis in-terdigitates with the orbital m. orbicularis oculi at the nasal level. It also blends with the obliquely oriented fibers of the m. corrugator supercilli. The corrugator is a small narrow muscle that arises from the inner extremity of the superior ciliary ridge and inserts into the deep surfaces of the skin above and between the orbital rims. It lies beneath the m. frontalis and m. orbicu-laris oculi. The corrugator draws the eyebrows downward and inward, producing the vertical wrinkles in the glabella. It is used to squint and protect the eyes. The m. procerus originates from the nasal bone and inserts into the skin of the forehead between the eyebrows. It pulls down the medial aspect of the eyebrow and produces the horizontal line at this level. The m. orbicu-laris oculi when contracted pulls the complete eyebrow downwards. (Table 5.3)
