Morphology and histology of the Anatolian bobcat ( Lynx lynx ) hard palate

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

Structural and ultrastructural characterization of the palatine epithelium of the Guinea pig: A new record of telocytes in the oral cavity

“…In Anatolian bobcat, caudally directed papillae are present on both the primary and secondary palatine ridges giving them a serrated appearance. In addition to a single row of conical papillae is present in the transverse groove separating the palatine ridges (Arı & Uslu, 2019). In brachycephalic dogs (Evans & de Lahunta, 2013) and tiger (Sarma et al, 2005), the palatine ridges have small blunt eminences.…”

“…In brachycephalic dogs (Evans & de Lahunta, 2013) and tiger (Sarma et al, 2005), the palatine ridges have small blunt eminences. The papillae on the palatine ridges, as well as the palatine raphe help to move the food backwards (Arı & Uslu, 2019).…”

Scanning electron microscopy of the palatine mucosa with connective tissue papillae of the Egyptian red fox (Vulpes vulpes aegyptiaca, Linnaeus, 1758)

The present study investigated the morphological, as well as the histological features of the Egyptian red fox's palate, in addition to the three‐dimensional characteristics of the connective tissue papillae (CTP) of the palate by scanning electron microscopy (SEM). The hard palate was narrow rostrally and its width increased caudally. The maximum width was located at the caudal border of the upper fourth premolar tooth. The incisive papilla was represented by a rounded median elevation surrounded on each side by a groove on which the oral openings of the incisive ducts opened. The rostral part of the hard palate had 9–10 caudally concave transverse palatine ridges while the caudal part appeared smooth without ridges. The palatine raphe was indistinct rostrally but formed a groove caudally. By SEM, the palatine ridges had low projections. Different microplicae systems were present on the epithelial surface of the incisive papilla, palatine rugae, interrugal areas, and the smooth part. The CTP of the incisive papilla, palatine ridges, and soft palate were conical‐shaped, cylindrical‐shaped, and parallel serrated ridges, respectively. Histologically, the hard palate was lined by a cornified stratified squamous epithelium resting on a dense connective layer of lamina propria while the soft palate was lined by a noncornified stratified squamous epithelium. The palatine salivary glands were present in the smooth part of the hard palate and the soft palate. The information presented in the current study might serve as a reference guide for the interpretation of pathological conditions of the palate of red fox.

“…The hard palate is formed of the incisive papilla, palatine ridges, and palatine raphe (Arı & Uslu, 2019;Mahdy, Abdalla, & Mohamed, 2018).…”

The present study investigated the hard palate of Rahmani sheep (Ovis aries). Samples from nine healthy adult male sheep were investigated using morphometrical, histological and scanning electron microscopic examination. Morphologically, the hard palate was elongated, narrow rostrally, and wide caudally. The incisive papilla was heart-shaped, flanked on both sides by a groove on which the nasopalatine duct opened. The palatine raphe was in the form of a groove that contained a ridge caudally. On both sides of the raphe, 13-15 pairs of palatine ridges were present and mainly occupying the narrow part. The wide part had a rough part that contains few ridges rostrally and a smooth part caudally. Histologically, the incisive papilla and palatine ridges were lined by a keratinized stratified squamous epithelium resting on a dense layer of lamina propria. The incisive papilla characterized by the presence of seromucoid salivary glands and hyaline cartilage fragments in the lamina propria. The salivary glands became abundant and well-developed in the wide part till the end of hard palate. All palatine salivary glands were Alcian blue-periodic acid-Schiff positive.By scanning electron microscopy, numerous gland openings were scattered on the surface of the palatine ridges. In conclusion, the hard palate of Rahmani sheep presented characteristic features, which may be related to the species differences, feeding behavior, and possible functional adaptations. This is the first study to report the presence of cartilaginous segments and salivary glands in the incisive papilla and provide detailed descriptions of the Rahmani sheep hard palate.
