MHS 234 Esophagus

Cuboidal Epithelia

The esophagus contains glands that secrete mucus to protect the esophageal lining. The glands empty into ducts that pass through the surface epithelium (stratified squamous epithelium, non-keratinized) to open at the surface.

The epithelial lining of glandular ducts varies with duct size:

  • : Found in small ducts
    • Cuboidal shape provides enough cytoplasmic volume to house the organelles needed for active secretion and absorption
    • Single layer allows for the efficient transport of substances across the epithelium
  • : Found in both small and large ducts
    • Cuboidal shape of the cells maintains some secretory capacity
    • Multiple cell layers (usually two) provide enhanced protection against mechanical stress and wear from increased fluid flow in larger ducts

In some areas where ducts are cut at an angle, the may appear more columnar in shape.
