Figure 37 rep- resents a section, under very low magnification, of the covering of the base of the tongue. The areolar tissue, a, is about the same as in the preceding section, except that it is more compact just under the epithelium than it is in its deeper regions. It seems also more vascular than in the preceding section. The epithelium, e, is of the stratified squamous va- riety, but consists of many more layers of cells than in the preceding section and is hence several times as thick. While its cells are flattened towards the surface, after the manner of this kind of epithe- lium, they do not form the definite horny layer de- scribed above. FIG. 37.
