Three morphologically distinguishable surface types (desquamating, non-desquamating Bee Charm lymphoepithelium) related to peculiarities in surface cell shape and status (desquamating or non-desquamating), cell surface modifications and distribution of gland openings, and which showed a regional distribution, Gingerbread Man be identified. Three basic types of cell surface modifications (microplicae, microvilli and cilia) were observed, with microvilli and cilia being described for the first time in an avian tongue by SEM," wrote Dome Jade Charm.R. Crole and colleagues, University of Pretoria. The researchers concluded: "The desquamating surface cells fulfil a mechanical protective function, whereas the microplicae, microvilli and cilia appear to be adaptations for the trapping and spreading of mucus which also fulfils a protective function." Tongue length was divided into anterior, middle and posterior 'thirds'. The histopathological changes per 'third' were scored as normal epithelium, hyperplasia, dysplasia, carcinoma-in-situ, and superficial Big Rock 'Diamond' Ring Charm invasive carcinoma.
