The luminal surface is completely covered by a number of finger-or leaf-like projections called villi, 0.5-1.5 mm in length.The core of a villus is an extension of the lamina propria, and its surface is covered by a simple columnar epithelium.he epithelium of the small intestine consists of the following cell types: ***The duodenum is distinguished by the presence of Brunners glands, which occupy most of the submucosa.*** In some areas these glands may penetrate the muscularis mucosae to enter the lamina propria.
