4.1.1 POJA-L4212
Title: Transition zone of esophagus to cardiac-zone of the stomach (human)
Description: Stain: Azan.
The arrow indicates to the abrupt transition of multilayered squamous non-keratinizing epithelium (1), characteristic for the upper part of the esophagus, into the single layered columnar epithelium (5) of the stomach.
(2): Lamina propria consisting of loose connective tissue fibers and cells.
(3): Lamina muscularis mucosae.
(4): Tela submucosa.
(7): Part of circular muscular layer.
(6): Glandulae cardiacae (mucinous). Note that the cardiac epithelium has folded to form crypts at the bottom of which the glands end. Remember that the striated muscles from the oral cavity gradually are substituted by smooth muscles upon extension into the upper quarter of the esophagus.
