Tongue: Circumvallate papillae

Each circumvallate papilla is surrounded by a deep, circular sulcus into which the serous glands of von Ebner empty. The connection between the duct of the glands and the sulcus is visible. The secretory cells of the glands contain apical eosinophilic granules; their watery secretions cleanse the surfaces of the taste buds for the reception of new tastes. 400x
