The |occipito-frontalis| is a broad musculo-fibrous layer that cover the epicranium (top of the |skull|). It consists of two thin layers of muscle. The occipital portion, sometimes called the occipitalis muscle, is quadrilateral in form and about an inch and a half in length. It covers the back of the cranium (skull). The frontal portion, sometimes called the frontalis, is also quadrilateral in form. It is broader and its |fibers| are longer. It covers the forehead. The frontalis and occipitalis portions of the muscle are joined together by a thin, flat intermediate ~tendon~ called the galia aponerotica. The aponeurosis is located above the occipito and frontalis muscle and covers the top of the cranium (skull). It works with the |occipito-frontalis| muscles to move the scalp. The frontalis muscle elevates the eyebrows and draws the scalp forward. The occipitalis muscle draws the scalp backward.
