Resumen

ZHU, Lei. Histological Study of the Oesophagus and Stomach in Grey-Backed Shrike (Lanius tephronotus). Int. J. Morphol. [online]. 2015, vol.33, n.2, pp.459-464. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022015000200009.

The microstructure of oesophagus and stomach in grey-backed shrike were examined by means of light microscopy. The results showed that the oesophagus glands were mucous glands, the shedding glandular cells and the mucin from the oesophagus glands secreted to the lumen. The number of the glands in the thoracic part was less than that of in the cervical part. The lumens of the glands showed an intense positive periodic acid-Schiff and Alcian blue reaction. There were two types of glands in the lamina propria. The simple tubular glands were located in the superficial lamella of the lamina propria, while compound tubular glands were located in the deep lamella. The epithelium was lined by a layer of cuticle in the intermediate zone between the proventriculus and gizzard. The surface of gizzard possessed a rough thick cuticle, which was made up of the Alcian blue-positive horizontal matrix and the periodic acid-Schiff-positive vertical rods.
