Study Notes
Mucosa
- Composed of three sub-layers: lining epithelium, lamina propria, and muscularis mucosae
- Lining epithelium: made of simple columnar epithelium or stratified squamous non-keratinized epithelium, sits on a basement membrane
- Lamina propria: loose connective tissue
Organ Folds of the Epithelium
- Esophagus: none
- Stomach: rugae (large folds) and gastric pits (small folds)
- Small Intestine: plicae circulares (circular folds) and villi (finger-like projections)
- Large Intestine: haustra (sac-like folds)
Specialized Structures in the Submucosa
- Esophagus: submucosal mucous glands
- Stomach: none
- Duodenum: Brunner's glands
- Ileum: Peyer's patches
- Large Intestine: none
