Occipital belly of occipitofrontalis
The occipital belly of the occipitofrontalis (also known as occipitalis, occipital part of occipitofrontalis, latin: venter occipitalis musculi occipitofrontalis) is a paired skeletal muscle of the head. It is a part of the occipitofrontalis muscle, and is connected with its frontal belly by the aponeurosis of epicranius.
The occipital belly of the occipitofrontalis originates from the superior nuchal line and inserts into the galea aponeurotica (aponeurosis of the epicranius).
Upon contraction the occipital belly of the occipitofrontalis moves the scalp posteriorly.
The occipital belly of the occipitofrontalis is innervated by the posterior auricular nerve, a branch of the facial nerve (CN VII).
