Resumo: | The morphology of the oral cavity of mammals relates to diet, habitat, and function. The palate is an important region with adaptations for oral somatosensation and mechanical loads due to the pressure of the tongue with food. The research aimed to describe the structural and ultrastructural characteristics of the epithelium and the connective tissue cores of the guinea pig palate using macroscopic, light microscopy, scanning electron microscopy, and transmission electron microscopy analysis. The hard palate had conical and filiform papillae, and the soft palate had open salivary ducts. After the removal of the epithelium, the connective tissue cores revealed thin filaments and laminar projections in the hard palate, and opening ducts were evidenced in the soft palate. The palatine epithelium was keratinized and organized by layers, lamellated corpuscles were found in lamina propria of the hard palate. In contrast, the soft palate had glands clusters associated with nerve fibers, and in both regions were identified telocytes. We concluded that the hard palate presented conical and filiform papillae that differ from other mammals. Besides, it is a new description of the connective tissue cores morphology and the first record of the telocytes in this anatomical region for mammals. |
