 Histoanatomical Study of Tongue in Maku strain mature goat

ABSTRACT: Macroscopic and microscopic evaluation of Maku breeds goat's tongue tissue. Twelve adult male and female goats were selected and their tongue was studied. The samples were stained by Hematoxylin and Eosin method. Macroscopic findings essentially were the same as the other goats but male Maku breed goat has a snow-white tongue, and the female's tongue is darker that probably due to a lot of melanin pigments. In microscopic findings the cup-shaped papillae was along with taste groove and serous-glands. Filiform, mushroom-shaped, cone-shaped, and lens-shaped microscopy were observed using optical microscope. The foliate papillae were not seen and almost a tick cuticle-layer around the papillae was observed. It must be noted that the intraepithelial taste buds were observed on top of mushroom-shaped papillae and on the side surface of the goblet papillae. The tongue is similar in both sexes in terms of size and structure.
