Mixed serous and mucous secretory units (40x
objective lens)
This section of the submandibular (submaxillary) gland shows a
mixture of unstained mucous secretory units
and serous secretory units with basophilic
cytoplasm. The mucous secretory unit have serous demilunes composed of serous
cells. Two intralobular ducts with walls of simple columnar epithelium are
located on the upper left. The dark-stained, flattened nuclei belong to
capillary endothelial cells.
