THE TONGUE 



The tongue of the ox is often variably pigmented. The root and body are 

 wider than that of the horse, but the free part is more pointed. The posterior part 

 of the dorsum forms a remarkable elliptical prominence, which is sharply defined 

 in front by a transverse depression. In front of this prominence there are large 

 and horny conical papillae (Papillae conicje), with sharp points directed backward;

they impart to the tongue its rasp-like roughness. The papillae on the prominence 

 are large, broad, and horny; some have a blunt, conical form, others are rounded or 

 flattened and are termed lenticular papillae (Papillae lenticulares) . Behmd the 

 prominence, the papillae are long and soft, i. e., not horny. The fungiform papilla 

 are numerous and distinct; they are scattered over the dorsum and edges of the 

 free part. The vallate papillae' number 8 to 17 on each side; they are smaller than 

 those of the horse, and form a long, narrow group on either side of the posterior 

 part of the prominence of the dorsum. The fohate papillae and the lingual fibrous 

 cord are absent. There are lingual follicles in the posterior part of the root and on
