“…Additionally, a simple cubic type epithelium was observed. The structural behaviour of the mandibular gland found in the present study is consistent with those described in African giant rats (Ikpegbu et al, 2013). In addition, serous semilunar structures and myoepithelial cells were found around the acini‐secreting cells and the intercalary ducts.…”

Rodents can present a large number of morphophysiological variations of the digestive system, allowing them to feed on different diets. In this context, the objective was to describe the morphology of the major salivary glands of Galea spixii. Gross dissection, light microscopy and transmission and scanning electron microscopy assessments of 12 specimens were carried out. The results demonstrate that the G. spixii has four pairs of major salivary glands (parotid, mandibular, zygomatic and sublingual). The glands are lobulated, composed acinar, consisting of mucous and serous acini, with the predominant parotid gland being serous and the zygomatic gland mucous. The mandibular and sublingual glands are mixed. The glands secrete acidic and neutral mucins and commonly present intercalary, striated and excretory ducts. The ultrastructure of the acinar cells suggests the presence of great cellular activity, with a cytoplasm taken by a rough endoplasmic reticulum, many mitochondria, vesicles of electrolucent nature and dispersed chromatin. In conclusion, the major salivary glands of G. spixii are constituted of mucous and serous acini, with serous acini predominant in the mandibular areas. The data also suggest that these rodents may adopt different types of diets, which may explain their adaptability to semi‐arid environments.

“…Histologically, the hedgehog parotid gland consisted of purely serous acini. This result is similar to those reported in the African giant pouched rats, European hamster, baboons, sheep, Zaedyus, rats and humans (Estecondo et al, 2005;Ikpegbu et al, 2013;Parks, 1961;Redman, 1994;Tandler & Erlandson, 1976;van Lennep et al, 1977). However, in studies that were performed on the parotid gland of squirrel monkey, and some carnivorous mammals including dog, cat and ferret, the parotid gland was reported to be seromucous (Poddar & Jacob, 1977).…”

This study aimed to investigate the major salivary glands in the southern whitebreasted hedgehog (Erinaceus concolor) histologically and histochemically. Five adult males were included in this study. The results showed that anatomically the shape of the parotid, submandibular and sublingual glands of the Erinaceus concolor was respectively almost pear, elliptical to pyramidal and oval. Histologically, the parotid gland had serous acini and secretory cells showed negative reaction to alcian blue (AB) (pH = 2.5) and negative response to aldehyde fuchsin (AF), methylene blue (MB) and PAS stains. The submandibular gland was a mixed gland of mucous and serous acini.The mucous acini were strongly positive for PAS, AB, MB and AF. However, serous acini were week for PAS and negative against AB, MB and AF stains. The sublingual gland was purely composed of mucous acini. The mucous acini of the sublingual gland were strongly positives for PAS, AB and MB methods. While their reaction to the AF staining was negative. In conclusion, the histological and histochemical observations of the major salivary glands of the southern white-breasted hedgehog (E. concolor) indicated that these glands shown similarities and some special different histochemical features as compared to other mammalian species.

“…Histologically, the parotid gland in the examined lowland tapir consisted of a number of large lobes, which were formed by purely serous alveoli similar to humans, horses, donkeys, domestic ruminants, neonatal Indian buffalo, southern white-breasted hedgehogs, rats, rabbits, mice, African giant pouched rats, European hamsters, baboons, Zaedyus pichiy, and African palm squirrels [1,5,7,9,[14][15][16]62,63,[73][74][75][76][77][78]. Quinterelli and Dellovo [32] also report that the parotid gland was serous in tapirs, although they fail to indicate the species.…”

“…Saliva is also rich in other ions (including calcium and phosphates) responsible for maintaining the balance between demineralization and remineralization, which play important roles in caries formation [5][6][7][8][9][10][11][12]. In addition, saliva is involved in the immunological response through IgA and plays a role in secreting potassium and resorbing sodium [13][14][15][16][17].…”

In terrestrial mammals, the parotid and mandibular glands secrete different types of saliva into the oral cavity. Both glands were obtained from two female lowland tapirs (Tapirus terrestris) and one female aardvark (Orycteropus afer) from the Wroclaw Zoological Garden (Poland) and examined by light microscopy (hematoxylin and eosin, mucicarmine, periodic acid-Schiff, Alcian blue pH 1.0, Alcian blue pH 2.5, Alcian blue pH 2.5/PAS, and Hale’s dialysed iron). Both the parotid glands observed in the lowland tapir and aardvark were compound alveolar serous secretory units, and in both species, the secretion was composed of neutral and acidic mucopolysaccharides (sialo and sulfated mucins). However, in both the lowland tapir and aardvark, a histological examination found the stroma of the mandibular gland was divided into very large lobes by poorly marked connective tissue. While many interlobar and striated ducts were found in the aardvark, very few were found in the lowland tapir. The mandibular gland was a branched tubular (mucous secretion) type in the lowland tapir, but it was a branched tubuloalveolar (mucous-serous) type in the aardvark. In all tested glands, the secretion was composed of neutral mucopolysaccharides, acid-sulfated mucosubstances, and sialomucins.
