Overview: Surface epithelium

The simple columnar epithelium lining the stomach is modified to form a sheet gland, with each cell in the sheet actively producing mucus that protects the stomach from its acidic environment. Mucin accumulates in the apex of each cell while the cytoplasm and nucleus are squeezed into the slender stem of the cell. 1000x
