Original investigationAnatomy of the tongue and microstructure of the lingual papillae in the fallow deer Dama dama (Linnaeus, 1758)
چکیده انگلیسی

The function of mouth organs in ruminants is connected with the process of rumination. To study morphofunctional relations, microstructures in tongues of 4- to 5-year old adult fallow deer were examined using scanning electron microscopy.When analyzing the tongue of the fallow deer, i.e. a ruminant classified as an intermediate mixed feeder between grass and roughage eaters, two processes were taken into account: (i) foraging and forage selecting, and (ii) chewing the cud during rumination to reduce particle size and improve digestibility.Microstructural results show that the above mentioned processes in fallow deer are important selection factors, which in the anterior part of tongue led to the development of clusters of fungiform papillae connected with preselection of food as well as a specific pattern of filiform papillae promoting increased adhesion of transported food. Massive and flattened conical papillae on the torus are arranged according to sideways jaw movements and are co-localized with flattened fungiform papillae and two rows of vallate papillae. Such an arrangement of papillae on the lingual torus presumably facilities distribution of ruminated food, with simultaneous transferring of taste signals about masticated food particles.
