Abstract:
A study was conducted on histological and histochemical feature of the hard palate of 32 broiler chicks at 7,11,18,25 and 32days of age. The tissues of hard palate containing rostral part of median palatine ridge, region of anterior maxillary gland, rostral region of choanal cleft and region having palatine papillae were collected. The results illustrated that the median palatine ridge presented a blunt papilla like appearance which sloped downward and backward was covered by stratified squamous keratinized epithelium. The median palatine ridge presented a blunt papilla like appearance which sloped downward and backward was covered by stratified squamous keratinized epithelium. The thickness of maxillary ramphotheca was increased with the advancement of age of birds. The epithelium showed the presence of keratin layer in the areas where the blunt papillae were present. Some of these papillae have the lamellated arrangement of the cells. At rostral region of choanal cleft a strong Alcianophilic reaction indicated the presence of the weakly acidic sulfated mucopolysaccharides, hyaluronic acid and sialomucins and glycogen. The respiratory epithelium was modified into simple columnar type of follicle associated epithelium (FAE) where the cells similar to the M-cells were also present.
