Left lateral exposure of temporal fascia.  For orientation, anterior is toward the top of the image and superior is toward the right border. A flap of skin and subcutaneous tissue has been reflected to expose the temporoparietal fascia (also called superficial temporal fascia) containing fasciculi of the posterior auricular muscle. A portion of the occipital artery can be seen superficial to this. This fascia joins the occipitofrontalis muscle and the galea aponeurotica connecting these muscle bellies and overlies the deep temporal fascia covering the temporalis muscle. The insertion of the sternocleidomastoid muscle into the mastoid process and superior nuchal line can be seen at the lower border of this image. (Image courtesy of M Nunez)
