The occipitofrontalis is the final muscle in this category of “other muscles of facial expression” and is associated with the scalp (see Fig. 8.56). It consists of a frontal belly anteriorly and an occipital belly posteriorly. An aponeurotic tendon connects the two:
The frontal belly covers the forehead and is attached to the skin of the eyebrows.
The occipital belly arises from the posterior aspect of the skull and is smaller than the frontal belly.
