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
