Histological features of MSGs in SD rats. The buccal (a), minor sublingual glands (b), soft palatal (c) and oropharyngeal glands (d) in rats were mucous. The acini were elongated and tortuous and so could be termed “tubulo-acini” (*). The duct system of the buccal, soft palatal and oropharyngeal glands were composed of the simple flat epithelium of the terminal ducts (single arrow) and excretory ducts (double arrow). The simple cuboidal epithelium (empty arrow) of the intercalated ducts were observed in the duct system of minor sublingual glands. *, tubulo-acini; A, acini; D, duct; E, epithelium layer of oral mucosa.
