Low Power Section Through the Submandibular Gland

At a lower magnification than that of the preceding image, it is easy to overlook mucous acini in the submandibular gland. The fat cells (A) help camouflage the mucous-secreting acini. The paler area in the center (B) of the field is several clusters of mucous acini. The cytoplasm of these cells stains faintly, whereas no staining is evident in the vacuolated fat cells.The majority of the cells stain darker pink and are forming serous acini. Note the numerous intralobular secretory ducts (C).
