| dc.description.abstract | [ENG] A collection of micrographs illustrating the organisation of the tongue in mice and rats. The stratified epithelium, connective tissue layers, muscular bundles, blood vessels, and nerves are shown in paraffin sections stained with hæmatoxylin-eosin or van Gieson trichrome. Semithin sections 2 µm thick were stained with toluidine blue. This collection complements the micrographs published by Dr Elena Sagristà i Mateo https://hdl.handle.net/2445/60015 — See also: https://diposit.ub.edu/dspace/browse?type=author&value=Sagrist%C3%A0+i+Mateo%2C+Elena | ca |

- Descripció:
- Transverse section of the body of a mouse tongue. The epithelium (ep) is thicker on the dorsal surface (top in the figure) and lateral surfaces, forming cone-shaped protrusions, the filiform papillae (asterisks). The epithelium on the ventral surface (bottom in the figure) is thinner and lacks papillae. Beneath the epithelium lies the lamina propria (lp), a connective tissue layer. This level of the tongue is close to its insertion into the floor of the oral cavity, and the ventral lamina propria (lpˬv) is thick and lightly stained, containing sections of the deep lingual vein (v, filled with erythrocytes). Beneath the lamina propria, a large mass of striated muscles is observed in transverse section: the superior longitudinal muscles (sl) dorsally, and the inferior longitudinal muscles (il) ventrally. Other muscular bundles are seen in longitudinal section: the massive transverse muscles (t) and the vertical muscles (ve), in thin bundles (nomenclature as in McClung & Goldberg, 2000). A portion of the genioglossus muscle (ge) which attaches the tongue to the floor of the oral cavity, is also visible. Paraffin section, hæmatoxylin-eosin stain. a, adipose tissue; ar, arteries.

- Descripció:
- Collage of two sections of the tip (apex) of the mouse tongue stained with hæmatoxylin-eosin (left) and van Gieson trichrome (right). The epithelium (ep) is distinctly stained in both micrographs, and forms cone-shaped elevations, the filiform papillae (asterisks). On the right (van Gieson), beneath the epithelium, the collagen fibres in the lamina propria (lp) are stained dark pink or red with acid fuchsin. In the left micrograph (hæmatoxylin-eosin), the lamina propria (lp) appears light pink and is difficult to distinguish from the underlying muscle fibres. In contrast, in the van Gieson trichrome (right) the fibres of the superior longitudinal muscles (sl), transverse muscles (t), and inferior longitudinal muscles (il) are stained brown and can be distinguished from the connective tissue (pink) in the lamina propria and that between the muscular bundles. Paraffin section, hæmatoxylin-eosin (left) and van Gieson (right). ar, artery; n, nerve branches; v, veins.

- Descripció:
- Dorsal surface of the mouse tongue in transverse section. The epithelium (ep) is unevenly thick, with conical protrusions, the filiform papillae (asterisks). In addition to the living epithelial cells stained purple, a stratum corneum (cor) of dead cells accumulates on the surface of the mouse epithelium (light orange). Immediately below the epithelium there is a thin layer of connective tissue – the lamina propria (lp) – stained pale pink, which projects into the epithelium contributing to the papillae (white stars). Deeper in the tongue there are bundles of skeletal (striated) muscles (st): massive bundles of the superior longitudinal (sl) and transverse (t) muscles and thin strips of vertical muscles (ve). Paraffin section, hæmatoxylin-eosin. ar, artery.
