The present study aimed at investigating the histological structures of the vallate papillae of the tongue of the dromedary camel. Samples were taken from the tongues of 5 healthy adult dromedary camels, then processed by standard routine histological technique. The vallate papillae were broad, encircled by a distinctive sulcus, and exhibited conca...

Context 1
... vallate papilla was broad, encircled by a distinctive sulcus, and exhibited a concave dorsal surface. It was covered by stratified squamous epithelium. Immediately beneath the epithelium was a well-defined lamina propria submucosa (Fig. ...
Context 2
... stratified squamous epithelium covered the papilla was either non-keratinized or parakeratinized. The non-keratinized epithelium was seen at the concave part of the dorsal papillary surface (Fig. 1). The parakeratinized epithelium was observed in the other regions of the papilla. The thickness of the epithelium varied distinctively according to the region. The greater thickness was seen on the upper surface of the papilla whereas the lesser one was located at the lateral surface of the sulcus (Fig. 2). (Fig. 3). The squamous layer ...
