    Comparative Investigation of the Morphological Structure of the Tongue in Lambs and Rams: A Macroscopic, Morphometric Light and Scanning Electron Microscopic Study
    (Wiley, 2025) Isbilir, Fatma; Kandil, Banu; Isbilir, Ihsan; Atli, Muhammed Zahid; Guzel, Baris Can
    The tongue, which has a unique mucosal structure, undertakes the task of taking food in living things, turning it into morsels, and transmitting it to the oesophagus. This study aimed to investigate the development of tongue papillae in young (lamb) and adult (ram) Hamdani sheep (Ovis aries) by comparing light and electron microscopic features and morphometric characteristics. Tongue tissues of 7 crossbred Hamdani lambs aged 4-6 months and 7 rams aged 1-2 years were used in the study. Tongues were evaluated macroscopically and morphometrically, and light microscopic and scanning electron microscopic descriptions were also performed. In addition to light microscopic identification, parameters such as papillae height, papillae width, epithelial height, and stratum corneum thickness were measured. The morphometric and histometric data were evaluated statistically. The results demonstrated age-related statistical differences in the number of fungiform and vallate papillae (p < 0.05). In rams, epithelial and papilla heights were higher for all papilla types, indicating that tongue tissue develops with age. The higher number of taste papillae in lambs suggests better taste perception in young animals, whereas the increased stratum corneum on filiform papillae in rams indicates more intensive use of the tongue during food intake. In conclusion, tongue papilla morphology shows age-related variations, with both lambs and rams exhibiting distinct morphological features across different papilla types.

    Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)
    (Wiley, 2026) Isbilir, Fatma; Kandil, Banu; Atli, Muhammed Zahid; Isbilir, Ihsan; Guzel, Baris Can
    This study provides a detailed characterization of the macroscopic anatomy and microscopic features (light and scanning electron microscopy) of the lingual papillae in the adult Anatolian wild boar (Sus scrofa libycus). Tissue samples were taken from two adult wild boars found dead in their natural habitat within an average of 1.5 h. Following macroscopic observation, samples underwent routine histological processing, histochemical staining, and high-resolution surface morphology analysis via scanning electron microscopy (SEM). Morphological analysis revealed five distinct types of papillae: filiform, fungiform, conical, foliate, and vallate. Filiform papillae, exhibiting either sharp or blunt apices, showed structural adaptations specialized for mechanical function. Fungiform papillae were identified in circular and oval forms; notably, taste buds were restricted to the circular type. Foliate papillae, comprising 3-5 distinct folds, lacked taste buds. A pair of vallate papillae, each demarcated by a prominent trench and housing lateral taste buds, was observed on the caudal tongue. Histochemical evaluation using Periodic Acid-Schiff (PAS) and Alcian Blue (AB) confirmed the presence of both neutral and acidic mucins within the lingual glands. These findings suggest that the lingual morphology of the Anatolian wild boar is closely adapted to its specific dietary habits and ecological niche. This data serves as a critical baseline for comparative anatomy, forensic veterinary medicine, and future morphological research.
