영문 초록

The tongue is a specialized vital organ. It aids in mastication, deglutition and food digestion. It also shares in the perception of taste sensation as it possesses various gustatory papillae. It is being subjected to numerous anatomical and histological examinations aiming at exploring the correlation between its morphological features and animal adaptations to various types of nutrition and environmental conditions. The goal of the present work was to compare the ultrastructural features of the filiform and fungiform papillae of three various mammals possessing different feeding habits; Egyptian mice, fruit bats and long-eared hedgehogs. Specimens were obtained from the tongues of four healthy adult animals from each mammalian type. Tongues were fixed and all the appropriate procedures were done to perform scanning electron microscopic investigation. Scanning electron microscopic examination demonstrated that in mice, there were four different sub-types of filiform papillae (spike, leaf, conical and tongue-shaped). In bats, there were two sub-types (flower and leaf-like) and in hedgehogs, there was only one type (tongue-like). These filiform papillae showed different distribution and orientation. As for the fungiform papillae, they were cylindrical in mice, rounded or conical in bats and dome-shaped in hedgehogs. Fungiform papillae possessed taste pores containing taste buds. Ultrastructural variations of the filiform and fungiform papillae were suggested to be probably due to adaptation to various feeding habits and different environmental conditions of these animals.
