Stain: hematoxylin and eosin. Medium magnification.

FIGURE 14.6 | Lower Esophagus Wall

(Transverse Section)

This low-magnification photomicrograph illustrates the lower portion of the

esophagus. The mucosa consists of a thick but nonkeratinized stratified
squamous epithelium (1), a connective tissue lamina propria (2), and a thin
strip of smooth muscle muscularis mucosae (3). Below the muscularis mucosae
are the esophageal glands in the submucosa, and closer to the stomach are the

esophageal cardiac glands in the lamina propria.
