Abstract:
The present study was conducted on tongue of 04 adult broilers. The tissues collected from the apex, body and root of the tongue including the caudal lingual papillae were processed for scanning electron microscopy. The apex had a large number of leaf-like papillae, some of which were exfoliated. Their free tips were pointed to blunt with sharp lateral borders. These papillae had longitudinal folds and the higher magnification presented micro ridges of different types. The density of these papillae was comparatively reduced towards a caudal portion of the body of the tongue. A transverse row of large-sized papillae was observed at the junction of the body and root. These papillae towards centre or medial part were pointed conical shaped and more fluffy and blunt type towards caudolateral portion. The size of these papillae also increased from the medial to the lateral side. The surface of these papillae had squamous cells which further showed microridges/microplicae of different patterns.
