Continuing from the stomach, the digestive tract becomes a smaller tube whose internal surface is much increased by means of folds--the plica circularis, the villi, and crypts of Lieberkühn. The plica (formerly known as valvulae conniventes) are really elevations of the submucosa covered on both sides by the entire mucous membrane-villi, glands, and muscularis mucosae. The mucosa membrane, or tunica mucosa, is lined by simple columnar epithelium in which many goblet cells are present, particularly in the deeper folds. The basement membrane, as well as the muscularis mucosa, are identical with those of the stomach.

Bachelors’ Theses
Anthers of Lilium formosum were collected ranging from the very young to the mature. Anthers used for the writing of this paper were gathered around Easter time or early April. The anthers were removed from the bud and the ends were cut off. Each anther was cut into three or four parts at right angles to their respective lengths. After the washing, infiltration, and imbedding was completed, sections were cut from eight to ten micra in thickness. Before staining the sections were placed in a solution of hydrogen peroxide to bleach for three hours. Flemming 's triple stain, a combination …
