“…These glands are also called the ventral buccal glands and are embedded in the buccinators anterior to the masseter muscle and lateral to the mandibles (Taib and Jarrar, 1989). The dorsal part of this gland consists of large lobules while the ventral part demonstrates a dark brown layer in the form of a pyramid.…”

“…Indeed, due to the arid environment, the plants grazed by camels are mainly xerophytes, characterized by small leaves often covered by wax, more or less spinous and usually rich in lignin (Fahn and Cutler, 1992). To consume such vegetation, the camel had to develop mastication, salivation and swallowing mechanisms based anatomically on tough and mobile lips together with a unique tongue able to pick desert plants small leaves (Taib and Jarrar, 1989). In addition, the dromedary has buccal internal dermis lined by compound keratinized epithelium covering a loose connective dense fibrous connective tissue (Tayeb 1950;Al-Asgah et al, 1990).…”

The aim of this study was to provide insight into the role of camel's saliva in protecting enamel against erosion and to evaluate the levels of salivary sodium, potassium, calcium, and phosphate ions among 2 groups of camels, those with low-grade tooth surface loss and those with high-grade tooth surface loss. Twenty-eight healthy camels, 5 males and 23 females, aged 20 months to 10 years, were divided into 2 groups. Group I comprise camels with “low-grade tooth surface loss” and Group 2 with “high-grade tooth surface loss.” Unstimulated saliva was collected by a draining method. The samples were then analyzed for sodium, potassium, calcium, and phosphate concentrations using automated chemistry analysis. Data were then statistically analyzed using the unpaired Student's t-test and Pearson correlation coefficient test. The study found the salivary calcium and phosphate concentrations were significantly lower in the “high-grade” erosion group, in comparison with the other group ( P < .0001 and P = .0257, respectively). The results also revealed that the more extensive the tooth surface loss, the more carious lesions the subject had ( P = .023), and that caries are more common in the anterior teeth, particularly the incisors. The authors conclude that alterations in inorganic elements of saliva, particularly the calcium and phosphate ions, play a major role in the development of resistance to tooth surface loss. This work may represent a direction for future research to develop custom-made preventive supplements, which can protect camelid teeth against tooth surface loss.

The one-humped camel is well-adapted to low nutritive resources, arid environments and desert ecosystems. Salivary glands have an essential role in moistening and swallowing the ingested food and forestomach digestion regulation and in water body homeostasis. The present study aims to find out the morphological, histological and histochemical characterization of the salivary glands of the dromedary camel concerning the salivation process's role in challenging the arid conditions and to mitigate the climate change impacts. Representative samples of the salivary glands of healthy 16 adult one-humped camel (Camelus dromedaries) of both sexes were tested including mandibular glands, parotid glands, sublingual glands, buccal glands, lingual glands, labial glands and palatine ones. The samples were processed according to the following handling: gross examination, fixation, dehydration, clearing, wax impregnation, embedding, trimming, sectioning, slide mounting, hematoxylin-eosin (H&E) and a battery of histological and histochemical staining. The salivary glands demonstrated variable types of tubule-acinar and tubule-alveolar secretory portions surrounded by numerous myoepithelial cells and armed with interlobular and intralobular ducts rich with goblet cells. In addition, the glands showed variable secretory cells (mucous, serous, mucoserous and mixed seromucous) with variable secretory products mainly mucusubstances, neutral mucin, acidic mucosubstances, sialomucins, sulphomucins, and2 9 T glycoproteins. Moreover, the glands collectively demonstrated activities for the following enzymes: dehydrogenases, phosphatases, esterases, carboxylases, aminopeptidases, peroxidases, cytochrome oxidases and carbonic anhydrases. furthermore, the glands exhibited alcianophilia and metachromasia. The findings of the present study indicate that the structure and the secretion of the salivary glands of the camel support an efficient salivation process and represent a strong challenge to growing water scarcity and expansion of xerophytes as the main pastoral resources for camels. In that sense, salivary glands in camels are one of the elements of his panoply adaptation to arid conditions and to mitigate the climate change impacts.
