ABSTRACT
The aim of this study was to investigate the histology of the tongue of the guinea fowl, Numida meleagris by using light and scanning electron microscopy methods. Six chicks (6-7 weeks), six layer hens (9-13 weeks) and six studs guinea fowl were used to study and determine the histological features of the tongue of the guinea fowl. Histological structures were examined using a light microscope the tissues and papillae of the tongue were examined with a the scanning electron microscope, and photos of the general histologic structures were taken. The tongue was triangular shaped, and consisted of apex, corpus, and radix sections. The dorsal and ventral surfaces of the tongue were covered by a keratinised stratified squamous epithelium. Lamina propria and submucosal layers were distinguishable underneath the epitelium. SEM observations of surface of the radix linguae revealed conical papillae and tongue caudally directed lingual papillae. Thus, in this study, the anatomy and histology of the tongue of the guinea fowl tongue were examined in detail using light and scanning electron microscopy, and the similarities and differences between the tongue of the guinea fowl and the tongue of other poultry species were investigated.
