“…The presence of serous and mucous glands in the lingual radix of the degu, as well as mixed glands in this area of the rat's tongue is undoubtedly related to the taste perception and swallowing of dry food, respectively. This was also suggested by Nagato et al (1997).…”

“…The lingual glands ducts were observed on the dorsal and lateral surfaces of the root in the Patagonian cavy (Emura et al 2011). Nagato et al (1997) focused on the Weber's salivary glands of the root of the tongue in the rat. These glands were tubulo-acinar (mixed), consisting of mucous tubules with serous demilunes.…”

“…The taste buds have been described in various rodents Ciena et al 2013;Kubota and Togawa 1966;Atalar and Karan 2011;Unsaldi 2010). There have also been studies that have described the lingual glands (Nagato et al 1997;Shindo et al 2006;Ciena et al 2013).…”

The tongue of an adult degu was examined by light and scanning electron microscopy. It consists of an apex, corpus, and radix and contains a lingual prominence. The aim of this study was to describe the course of muscle fascicles of the proper lingual muscle, the presence and nature of the lingual salivary glands, and particularly the appearance and distribution of the lingual papillae. Three major types of papillae have been observed: filiform, conical, and vallate. The dorsal surface of the lingual apex extends in caudally bent filiform papillae with two spines. The lingual corpus bears long filiform papillae with a single tip. The lingual radix contains crown-like papillae in the region of the prominence and conical papillae in the remaining areas. Two oval vallate papillae were discovered caudally on the lingual radix. This first description of the lingual structures in a degu could be used for comparative studies or as basic data for differentiation of lingual morphology in this species.

“…The ultrastructure of rat Weber's glands has been described exquisitely by Nagato et al (1997). In addition to the features described above, it was observed that the serous demilunes have direct access to the lumina of the mucous acini that they cap and no secretory canaliculi were seen.…”

“…Nagato et al (1997) attributed the foci of fused secretory granules in some mucous cells in Weber's glands to this phenomenon. This would be consistent with the suggestion by Eldar and Elowsitz (2010) that differences in responses among cells performing the same function, some quick and others slow to react to stimuli, allows for sustained levels of performance during long periods of activity.…”

In this article the locations and histologic and ultrastructural features of all of the minor salivary glands of the rat are presented; similarities and differences among them are highlighted. These glands are almost as diverse morphologically as the major salivary glands of the rat. The acini of von Ebner's glands are serous; those of the anterior and posterior buccal glands and minor sublingual glands are mucous; and those of the glossopalatal, palatal, and Weber's glands are mucous with serous demilunes. The anterior buccal, minor sublingual and von Ebner's glands have striated and stratified columnar ducts, while only the minor sublingual and von Ebner's glands have intercalated ducts. The glossopalatal, palatal, posterior buccal and Weber's glands have none of these ducts; the tubulo-acini drain abruptly into short terminal ducts composed of stratified squamous epithelium. All of the mucous acini react with an antibody to a mucin (Muc19) of the rat major sublingual gland, but in some of the glands the reaction varies in intensity among the acinar cells. Ultrastructurally, the mucous secretory granules of the anterior buccal, glossopalatal, palatal and Weber's glands are biphasic, while those of the minor sublingual and posterior buccal glands are monophasic. Although there is a considerable body of literature concerning the development, innervation, physiology and proteomics of von Ebner's glands, investigation of the other minor salivary glands of the rat ranges from modest to nearly nonexistent.
