Estudio comparado de las Papilas linguales del Gato (<i>Felis catus</i>) y del Conejo (<i>Oryctolagus cuniculus</i>) mediante el Microscopio electrónico de barrido

Abstract

Summary Compared studies of the lingual papillae of the cat ( Felis catus ) and the rabbit ( Oryctolagus cuniculus ) by scanning electron microscopy The morphologic characteristics of the principal lingual papillae of the cat and the rabbit were studied and compared through the use of scanning electron microscopy. The fungiform papillae of the rabbit demonstrates an annular pad which is absent in the cat. Both species demonstrated openings of taste pores on these papillae. The vallate papilla demonstrated pseudopapillae in both species. In the rabbit, however the annular pad is quite rudimentary. These papillae also demonstrate taste pores on their surface in both species. The foliate papillae were quite different between the species. In the cat, they were digitiform and in the rabbit they were represented by a number of laminae. Few gustatory pores were observed in the cat, but pores were numerous in the rabbit. In both species there were three forms of mechanical papillae (smooth conical, scaly conical and filiform). These papillae are described according to location and density.
