Cells which are specialized to secrete mucus are called mucous cells. Examples include secretory cells of the salivary glands, esophageal glands, stomach surface, pyloric glands, and Brunner's glands of the duodenum.These cells are typically organized into tubular secretory units.erous cells of the pancreas and the salivary glands are typically organized into secretory units called acini. In routine light microscopy, serous cells are distinguished by basophilic basal cytoplasm, a centrally-located nucleus, and variously-staining secretory vesicles (zymogen granules) in apical cytoplasm.
