title: Localization, morphology and ultrastructure of taste buds in the domestic duck (Cairina moschata domestica L.) oral cavity.
abstract: The Authors report on localization of the taste buds in epithelium of the palate (70%), the floor of the oral cavity (28%) and the tongue (2%) in Domestic Duck. Each taste bud is oval-shaped, measuring roughly 130 x 60 microm, and communicates with the oral cavity by a short duct. There is topographical correspondence between the buds and the parietal salivary glands. Ultrastructural examination showed the following 4 cell types: 1) light cells--characterized by cytoplasm containing sparse perinuclear filaments, numerous light vesicles, a uniformly granular nucleus. 2) dark cells--with electron-dense cytoplasm, numerous perinuclear filaments, occasional light vesicles, an irregular and densely granular nucleus. 3) intermediate cells--with characteristics common to the two previous cell types. 4) basal cells--located at the ventral part of the button.
