    Taste bud density in circumvallate and fungiform papillae of the bovine tongue
    (Murcia : F. Hernández, 1990) Dasgupta, Kaberi; Singh, Amreek; Ireland, William P.
    Taste bud quantitation may provide useful parameters for interspecies comparisons of the gustatory system. The present study is a morphometric analysis of bovine taste papillae. Circumvallate and fungiform papillae from six bovine tongues were serially sectioned and, following staining, analyzed. Circumvallate papillae were found to have a mean volume of 3.66 * 2.82 mm3, a mean number of taste buds per papilla of 445 f 279, and a mean taste bud density of 155 112 buds/mm3. Values for lateral fungiform papillae for the same three parameters were 0.384 f 0.184 mm3, 13.2 f 13.4, and 40.8 * 46.6 buds/mm3, respectively. Values for dorsal fungiform papillae were 0.438 f 0.246 mm3, 4.39 f 4.78, and 14.0 f 17.1 buds/mm3, respectively. Circumvallate papillae were found to have a significantly greater volume, number of taste buds per papilla, and taste bud density than either type of fungiforrn papilla. These data should serve as background for biochemical, endocrinological, or neurological studies involving the bovine tongue
