Abstract
Von Ebner’s lingual salivary glands secrete through multiple ducts into the clefts of the circumvallate and foliate papillae. At the microscopic level, gland acini are filled with secretory granules.’ Since 80% of the lingual taste buds are contained in the foliate and circumvallate papillae in the rat: and since taste receptor sites on the microvilli are bathed in saliva: these glands provide a microenvironment important in taste transduction in posterior tongue taste buds. Little is known concerning the neural control of von Ebner’s glands. Recently we have shown that the source of their parasympathetic control is via cells in the inferior salivatory nucleus in the medulla? We now have applied the morphometric methodology used by Getchell and Getchell’ in a study of Bowman’s glands to characterize the extent of /3-adrenergic control of the von Ebner’s gland acini.
