(Redrawn after Braus.) and tunica adventitia; but the serous layer which covers the stomach and intestine is wanting in the esophagus, since the body-cavity Uned by the serosa does not extend into the neck. The tunica mucosa includes not only the stratified squamous epithelium which lines the esophagus, but also a connective-tissue tunica propria and a muscularis mucosae, a thin layer of longitudinal muscle fibers. The muscular coat of the esophagus consists of striped fibers in the upper third, while those of the lower two- thirds are smooth. (Fig. 214).
