Scanning electron microscopic study of the lingual papillae of the one humped camel, Camelus dromedarius

The dorsum of the camel tongue shows filiform, fungiform, circumvallate and special (wart-like) papillae. Filiform papillae are conical in shape and show different heights and thicknesses at various levels. Fungiform papillae are rounded and are surrounded by robust filiform papillae. They can also be observed on the tip of the ventral surface. They have taste pores on their surfaces. Circumvallate papillae are encircled by a primary groove and an annular pad. Their taste pores open into the grooves. A special type of filiform papillae is wart-like and has been observed on the posterior portion. These do not show taste pores.
