The intestinal epithelium is part of the intestinal mucosa. The epithelium is composed of a single layer of cells, while the other two layers of the mucosa, the lamina propria and the muscularis mucosae, support and articulate the epithelial layer. To securely contain the contents of the intestinal lumen, the cells of the epithelial layer are joined together by tight junctions, thus forming a contiguous and relatively impermeable membrane. ct angio pe ct angio neck with contrastCauses of crypt branching include: inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease ), persistent infectious colitides, and ischemic colitis.
