The Occipitalis, thin and quadrilateral in form, arises by tendinous fibers from the lateral two-thirds of the superior nuchal line of the occipital bone, and from the mastoid part of the temporal. It ends in the galea aponeurotica.

It is considered by some sources not to be a muscle of its own, but to be a part of the occipitofrontalis muscle.
