ABSTRACT
The dorsal surface of the tongues of the Slow Loris and the Pygma Slow Loris were examined by employing scanning electron microscopy techniques. Three types of the papillae are present on their dorsal surface of the tongue filiform, fungiform and vallate. The filiform papillae are located the apex and the body of the tongue, and we observed that each of them has a gustatory pore. The fungiform papillae, scattered singly among the filiform papillae, distribute mainly on the apex of the tongue. The vallate papillae are located along the diversing arms of the V-shaped boundary between the anterior and posterior regions of the tongue. In addition, no foliate papillae were observed. The morphological characteristics of the dorsal surface of the tongues in Slow Loris and Pygma Slow Loris are similar to each other.
RESUMEN
La superficie dorsal de la lengua en lori perezoso y lori perezoso pigmeo fue examinada utilizando técnicas de microscopía electrónica de barrido. Se observaron tres tipos de papilas presentes en la superficie dorsal de la lengua filiforme, fungiforme y valada. Las papilas filiformes se localizaban en el ápice y en el cuerpo de la lengua, y observamos que cada una tenía un poro gustativo. Las papilas fungiformes están distribuidas individualmente entre las papilas filiformes, principalmente en el ápice de la lengua. Entre las regiones anterior y posterior de la lengua se observan las papilas valadas a lo largo de las extensiones del margen en forma de 'V'. Además, no se observaron papilas foliadas. Las características morfológicas de la superficie dorsal de las lenguas en lori perezoso y lori perezoso pigmeo son similares entre sí.
