Abstract
In order to know the comparative histological structure of the tongue of some domestic and laboratory animals, the root of the tongue has been investigated by light microscopy. The filiform papillae were mainly distributed in the root of the tongue of most animals and many foliate papillae were also found in the dog and rabbit. On the other hand, only filiform papillae were found in the fowl. The very well-developed mucosa was found in the cattle and in the dog, fowl, rat and mouse was fair. The lamina propria was well developed in the cattle, dog and pig, The muscle layer was well developed in the cattle. The adipose tissue which distributed between the muscle fibers was mainly found in the dog. The lingual glands were well developed in the pig, fowl and rabbit. The properties of these glands were shown strung acid mucopolysaccharide in the dog and pig, weak acid mucopolysaccharide in the fowl, rabbit and rat and neutral or acid mucopolysaccharide in the mouse. The species differences on the histological structure of the tongue were also ascertained by light microscopical observations.
