Morphostructural characteristics of the vallate papillae in Bos taurus.

The Morpho-structural characteristics of the vallate papillae of the bovine tongue were studied utilizing LM, SEM and TEM techniques. In the bovine, the vallate papillae are numerous and different in size. They have a prominent vallum papillae which surrounds a deep sulcus papillae. The sulcus has many elongated taste buds on its inner wall. Nervous fibers enter the taste bud and sometimes have rosary shaped axons. The gustative sensitivity of these animals may be instrumental, in their choice of food and avoidance of noxious plants.
