Compound tubuloacinar gland

Mucus-secreting cells are easily distinguished from those releasing a serous product. Mucous cells are frothy in appearance and are arranged as tubules with wide lumens. Serous-secreting cells can be arranged as acini or as serous demilunes. Each acinus has a small lumen surrounded by wedge-shaped cells with secretory granules. Serous demilunes possess similar cells, but they are configured as crescent-shaped units capping the ends of tubules. Submandibular 1000x
