| Abstract (English): |
The anatomy and histology of the tongue of Centurio senex, a frugivorous bat, were reviewed to look for any special structure associated to its feeding habit, and to compare it with other bat species with different alimentary habits, documented in other manuscripts. The tongue is short and rounded shape, on its surface there are numerous short single-pointed papillae on the first half, and large papillae at the middle of the surface; near the tip there is a small group of bicuspid papillae; fungiform and circumvallate papillae are absent. Histologically at the part of the tongue, there is a septum with one symmetrical pair of veins, arteries, and nerves at both sides of it, this particular arrangement indicates the intraoral use of this tongue. There are some lymphatic vessels among the muscle fibers, which are the first record of this kind of structures in the tongues of bats; also lymphatic nodules were found similar of those present in Balantiopteryx plicata. The large single-pointed papillae and the lymphatic vessels and nodules are the only specialized structures found in this bat species. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
Se analizó la estructura anatómica e histológica de la lengua del murciélago frugívoro Centurio senex, y se comparó con la descrita para otras especies de quirópteros, para conocer si existen estructuras particulares que pudieran estar asociadas a su tipo de alimentación. La lengua de este murciélago es corta, redondeada y posee numerosas papilas filiformes unicúspides, las cortas se ubican en la parte anterior y las largas en la parte media, y cercano a la punta se encuentran pequeñas papilas filiformes con ápice bicúspide; carece de papilas fungiformes y circunvaladas. A nivel histológico, en la parte de la lengua hay un septo fibroso vertical y a ambos lados de él, vasos sanguíneos y nervios en posición simétrica, este arreglo indica que la lengua tiene función intraoral. Entre las fibras musculares estriadas de la parte posterior hay algunos vasos linfáticos, siendo éste el primer registro de la presencia de dichas estructuras en lenguas de murciélagos; también se encontraron nódulos linfoides como en Balantiopteryx plicata y Noctilio leporinus. Las papilas filiformes alargadas y los vasos linfáticos son las únicas estructuras especiales encontradas en Centurio senex. [ABSTRACT FROM AUTHOR] |
