Bovine von Ebner's glands were studied by electron microscopy. The gla
nd consists of tubulo-alveolar adenomeres which open into an abbreviat
ed duct system. The cells of the secretory acini show many morphologic
al features typical of serous cells and contain numerous granules with
a complex substructure. Short intercalated ducts connect the acini wi
th excretory ducts which are lined with bistratified epithelium. The s
triated ducts are absent. The von Ebner's gland morphology was compare
d with that of the same gland in other species of mammals and with the
ultrastructure of the major bovine salivary glands.
