To study the dorsal surface of the @entity1 tongue using a @entity4653 ( @entity4653 ), tissue specimens were taken from the anterior part of the tongues of 15 individuals aged from 21- to 28-years-old. The @entity406 -fixed samples were processed routinely for @entity4653 . With @entity4653 the surface of the normal tongue mucosa was shown to be rather evenly covered by filiform papillae, with some @entity1829 scattered among them. @entity1829 consisted of two parts: the body and hairs. The mucosal surface of the body was smooth; the squamous epithelial cells were polygonal, and their boundaries were prominent. On the surface of the superficial epithelial cells were parallel or branching microplicae. Each filiform papilla had 6-10 hairs, which were scaled and covered by an extensive plaque of microorganism. The upper surface of the @entity1829 was smooth; only a few desquamating cells were seen. The superficial cells had a pitted appearance and cell boundaries overlapped. Taste pores, up to 3 pores in a single papilla, were found on the upper surface. Desquamation was more pronounced on the base of the @entity1829 than on the upper surface. In almost all @entity1829 some hairs protruded from the base. Parallel microplicae were found on the surface of the superficial cells of the base. The structure and function of the @entity1 tongue, as well as the microplicae of its superficial cells, are compared to those of various species of animals.
