The occipito-frontalis is a broad musculo-fibrous layer that cover the episkull. 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 originates from the occipital bone, covers the back of the skull and inserts in the galia aponeurotica. The frontal portion, sometimes called the frontalis, is also quadrilateral in form. It is broader and its fibres are longer. It originates from the galea aponeurotica, covers the forehead and inserts in the skin of the eyebrows and nose. The frontalis and occipitalis portions of the muscle are joined together by a thin, flat intermediate tendon called the galia aponeurotica. It is located above the occipito and frontalis muscle and covers the top of the skull. The occipito-frontalis muscle is innervated by the facial nerve and is supplied by the occipital artery. The galia aponeurotica 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. Research Occipito-Frontalis
