Abstract:Except at the tip of tongue, there are many lingual glands in the lamina propria of the tongu, of the Chinese alligator. The gland are mainly distributed on both sides of the midline at the dorsal surface of the tongue. Some are simple tubular glands and others are complex acinotubular glands. Total numbers are about 100 throghout the tongue. The epthelium mucosa is involved to form the excretory duct and gland alveolus in the development of the lingual glands. The glands near hatching time of the embryonic alligator. The lingual glands first appear at about one thirds on the tongue, and then appear at the posterior portion. They are still developing at about one mouth old. The function of the Chinese alligator's Lingual gland is to secrete NaCl and to lubricate food.
Keywords:Alligator   Lingual gland   Morphology   Development   Function.
