AB  - The histological organization and histochemical aspects of the pharyngeal jaw 
      apparatus of the Indian major carp Cirrhinus mrigala are described. The 
      pharyngeal jaw apparatus consists of a lower pharyngeal jaw and a chewing pad. 
      Histochemical analysis reveals that the epithelium covering the lower pharyngeal 
      jaw is mucogenic and is involved in the secretion of different classes of 
      glycoproteins (GPs) including GPs with oxidizable vicinal diols, GPs with 
      O-sulphate esters and GPs with sialic acid residues with and without O-acyl 
      substitution. Characteristically, the epithelium at irregular intervals is 
      differentiated into simple or branched tubular pharyngeal glands, which often 
      extend deep into the sub-epithelial tissues. Copious mucus secretion from 
      pharyngeal glands may be associated with transportation of chewed food particles 
      toward the esophagus. Histochemistry and fluorescence microscopy show that the 
      epithelium covering the chewing pad is keratinized. The keratinized surface of 
      the chewing pad may be considered to serve as an occlusion surface for the lower 
      pharyngeal jaw teeth forming an efficient pharyngeal mill for chewing food 
      materials.
